Joe,
I don't know what you have done to date so I probably will go over stuff you already know.
The following info is based on a long quest to drink only good coffee. It describes how to make coffee I like. Use at your own peril, consult a physician if shakes persist.
1. Start with the coffee beans. Make sure that they are 100% Arabica, no Robusta beans unless you like really bitter coffee. IMO Robusta beans make the coffe taste cheap or stale.
Never buy coffee from your supermarket, who knows how old it is? Find a local or as close as possible roaster of beans. Down here any small roaster will have a café as part of the business. Ask their opinion, try the beans or grind in a coffee made by them. Your coffee at home should taste similar (perhaps not as good - depends on your equipment).
I do not grind my own coffee but get a smallish bag ground by the roaster. He has a good grinder. I do not. A weekly purchase of coffee grind makes better coffee than stored coffee. Small amounts do not need to be refrigerated, the coffee tastes better if it starts at room temperature. My roaster says; "Do NOT refrigerate my coffee". Vacuum storage if you have to.
The grind must be fine for an espresso. From the supermarket it is often too coarse and designed for plunger or (heavens forbid) dripolator. Not too fine, you'll clog the machine.
I personally love my beans to have a dark (dark dark) roast. I have a little sugar (white) to offset the bitterness. I detest medium roast beans. Lots of people like think that they are yummy. Up to your flavour buds.
2. To get crema the superhot water (preferably not steam) needs to be forced through the grind, under pressure, from above, to extract the oils which make the crema. Most stove top espresso machines are not designed this way. It is possible to get reasonably good coffee from traditional (scew apart) stove top machines but crema from these machines is minimal. Unless you have an Atomic or simlar design or the machine pours the coffee straight into a cup. Transferring from a jug to your cup will lose that crema.
I prefer electric (with a pump, not a just a pressure boiler) espresso machines. You can get close to café quality espresso from most (well designed) home (electric) espresso machines.
3. Tamp. Get a little plastic tamper (tampa?). This is a key step. Load the coffee and gently compress it with your tamper. The plastic ones that are cheap do the same job as the stainless steel expensive ones.
4. If the water from your taps tates no good, don't use it to make coffee. Get a filter (for your water)
5. Keep your machine Clean.
So, there you go. Easy.
Good beans.
Good machine.
Tamp.
Good water.
Clean machine.
Finally experiment with different beans and roasts. I get my roaster to slighty tweak the grind on the coffee I buy to suit my machine.
Be patient. A good espresso should take between 15 to 30 seconds to come out (these numbers are hearsay but do seem to work). Vary the amount of coffee you load and the amount of pressure you use when you tamp the grind until you are happy.
Hmmmm. Now I need a coffee.
