Will you be based in UB? If so, good for you. 
Outside UB, everything will be difficult to get, even toilet paper.
Laptops are expensive in Mongolia. It'll be easier and a lot cheaper to bring one from home.
Stay far away from film labs in UB. They only process colour film, and not very good at that. Your film WILL get scratched.
Mongolia is a hugely dusty place in Spring and Summer, and a very air-polluted places in Autumn and Winter. Keep that well in mind for your equipment and your own health. Eye problems are very common in Mongolia.
Mongolia is also a place where even the barest of essentials are getting more and more expensive. Try to bring your personal luxury from home. You'll need it. Mongolians don't understand this "Western" need for the bare essentials as many are forced to live like that out of necessity. And whatever they have, they take with them when they move.In the countryside this literally means loading everything on a big truck, including children.
I bring my laptop, my R-D1, my Canon Eos 300D, a couple of lenses for each body, and plenty of everything else whenever I go there. You won't be able to buy (rangefinder) cameras and lenses in UB, or get them fixed. You'll be on your own when you don't have a spare. Internet is available everywhere in UB. Mobile phones can be used through much of Mongolia, oddly enough; plus they're much more reliable than line phones.
Credit cards can be used in UB in more and more places, plus you can draw money from ATM's in downtown UB every 100 meters.
Outside UB... have plenty of cash (dollars, euros, and the local tugrik) in small bills on you 'cause your credit card won't serve you there.
UB is a great (though not very clean or pretty) place to be. But most of Mongolia is wild: from tranquil rolling steppe to wind-swept, snow-covered mountain ranges to large forest infested with wolves, bear and other wild animals. Don't take hiking out lightly.
My personal opinion is that foreigners should try to stay away from other foreigners as much as possible. Try to build up slew of Mongolian friends and try to fit in. Don't be their trophy foreigner.
And... most Mongolians don't wear traditional clothes anymore, except for the "gutal" perhaps and the "deel" on festive days.
Be aware of your personal belongings when your going to the "Xar Zag" (Black Market), the railway station, bus stations and bus stops. Pickpocketing is rife in those places. I learned the hard way.
Don't get into a fight! Mongolian men in general are far stronger that most Westerners. And from young they've been wrestling with each other, working hard and heavy. Also, don't drink too much with strangers. Nearly every Mongolian man and many women can hold their liquor very well. Be careful with drunks and street kids. Unpredictable.
Don't be the "foreigner who'll save the world". There are many poor people. Especially the elderly have it rough oft times. Don't encourage begging. In stead, make phone calls from the street. Buy sweets, socks, and sigs from the street. Get weighed once in a while.
Be aware that taxis can very well have a rigged, broken or no meter. If you have a regular route, make a mental note of the average price and try to get a ride without the meter for a fixed sum. Traffic was (still is?) atrocious 2 years ago, with some improvements here and there being implemented. Getting stuck in traffic is a real hazard, so take your time when going places.
Do go see the Zanabazar museum, the National History and Natural History museums. And do visit a traditional music performance.
Take a trip to Zaisan and the Buddha statue. And to Mother Rock and the nearby temple complex some 40 KM south of UB.
Terelj is a nice place for a day trip and a picnic, or for a few days stay.
Erdene Zuu is the temple at the site of the former imperial capital Karakorum (Xar Xorin). Great place to go to (one day to, next day back, for instance). Hotels outside UB are total crap, btw.
Naadam is 11-13 July. Try to be there. I will.
To me the best places in UB are the Gandan monastery and the Choijin Lama museum temple. Try to go to Gandan early in the morning to attend "mass". Choijin Lama museum is much much smaller than Erdene Zuu but once you've seen Choijin Lama Erdene Zuu may seem a little disappointing.
Cool place further away is Khujirt. Try to stay at the State resort or the (rather good!) privately owned resort next to it. It's a health resort: mud baths, massage, etc. And the area is great to. From Khujirt there are a number of interesting places that can be visited in a (very long) day, like the Orkhon waterfall, Erdene Zuu, and another old temple complex in the mountains (I forgot the name) down the Orkhon river.
For the rest, rely on your Mongolian friends to take you places. They know where to go, how to get there, and when to go there. Especially friends with partner and kids will often take a weekend break outside UB or go to Bogd Khan Uul in winter for sleighing down the slope. Really cool, btw, at -30 degrees C.
Anyway, enjoy your stay. I'll be there from 3 (4?) July until the end of that month. Maybe we can meet some time.
