Record everything dry. Add the effects in during mixdown. Gives you much more control over texturing, etc...during final mixdown. A stereo outboard compressor is a very good idea, especially for vocals. Furman and Symetrix are two good companies that come readily to mind. (I believe they both have websites.) PZMs are good, but can be awkward for recording acoustic instruments, because you have those thin attachment cords dangling either off of a mike stand or having to place them somewhere imoveable. My experience with them is that they tend to work better for live taping of stage performances. One on either side of the stage for a good general wash. Radio Shack carries them and they are affordable. You'll have to experiment with all this, and that is at least half the fun, and educational as well. Best of luck and enjoy. I've had my own home recording studio for years, and know the buzz you are currently experiencing. It's a great thing to have at your disposal. Best of luck.
