Hi,
whether shutter speeds should only be set after winding on the Kiev 88 is a matter of some debate. It's a bit complicated because people don't usually specify whether they're referring to unmodified Kiev 88s or to "improved" models with different, "tuned" shutter mechanisms or with mirror lock-up added. That's why there are so many conflicting reports.
On my 1985 Kiev 88 body with an unmodified shutter mechanism, I can turn the speed wheel both ways and it makes no difference if I set shutter speeds before or after winding.
On the other hand, for example there was a series of early MLU Kiev 88's by Hartblei where both would break the shutter instantly. This is why the remark is in the Arax manual.
In general, it's probably good practice to stick to the same routine as with early FEDs and Zorkies, that is: change shutter speeds only after winding (and only set shutter speeds by turning the wheel clockwise). Even if it makes no difference with your particular Kiev 88 body, building up this kind of routine could help you if you ever use other FSU cameras or if you ever get to shoot with a friend's modified Kiev 88.
The Kiev is a great camera. Well, it's not really that great, but it's enormous fun to shoot with and the optics are cheap. I love mine and have taken some of my best pictures with it. The best thing is the cheap glass; I have bought a 3,5/65 for 65 EUR, a 4/50 MC Flektogon which is outright amazing for 120 EUR and a 2,8/180 Sonnar for 45 EUR. It's simply impossibly to beat this with any other medium format system. However, to use those, you have to have your Kiev 88 modified and fitted with a Pentacon Six mount, which is somewhat expensive.
If you're seriously interested in medium format SLRs, you might look at either the Kiev 60 (which is bigger and has no exchangeable backs, but also less trouble with the same, and is considerably more sturdy and has a Pentacon Six mount for using Carl Zeiss Jena lenses) or used Bronica or Hasselblad 500 gear. Both of the latter are technically better cameras, and gear has become available at low prices because of professionals ditching these systems for digital. Glass is somewhat more expensive, though. The nice thing about the Bronica is that it has a focal plane shutter and a dual lens mount, which makes it easy to adapt all kinds of weird lenses from other cameras (folders, large format or whatever).
