The first thing you want to do is NOT to line the walls. The first thing you want to do is to go to all the thrift stores and garage sales and buy a bunch of big ugly living room pillows -- kinda dead ones, not too bouncy. Stick them in all the corners. Gravity will hold them in the floor corners and you can use a little American ingenuity (if you are American) to tie them into the ceiling corners.
When you want to create a dead wall (behind the drums if you use a human drummer), use Thermafiber. It is excellent and sells for building-materials prices, which isn't much. Two-inch thick minimum, three if you can swing it. Just cover one wall with it, and part of one of the adjacent walls. It looks like Fiberglass but doesn't have the itch problem. It is like molded cotton candy. Don't eat it.
Don't use a booth for vocals. You'll get ugly resonances you can't get rid of. Just get the biggest quiet space you can (is your bedroom upstairs?) and use that.
Mix with good headphones, then re-tune the mix from listening to it on a few loudspeaker situations.
I'm not making this up. It took me years to get this down. Just do it. You'll be fine.

I appreciate your thoughts as well. The pillows sound like just the sort of mischief for me to get into. Do they have to be nasty, old couch cushions? Because target sells nice, white, new pillows for $5 ... Is the dense behavior critical? If so, how to "age" new pillows in a hurry ... hmm ... :-D
I'll also look into thermafiber. I have been using the studio as a vocal booth as well, since it is only the size of a bedroom anyway. If I put thermafiber only behind the drumset, would it "kill" the space for vocal recording?
Thanks again!
Well, you do want the space to be half dead.
It's an old hi-fi thing that you want the wall directly behind the source of sound (so you don't get blurry early reflections) and the other walls a little bouncier.
But a room that is a little dead on one side and a little live on the other is a good room.

I went out and bought 106' Sq of fiberglass insulation, 10" thick. One wall is 12' wide and ~8.5' high, so I could make that wall my 'dead' wall. I was planning to let it hang from the ceiling in strips, and I could staple it to the wall near the ceiling. The staples would compress it, but it would only do that where I staple it, hence stapling it high and letting it hang. I paid extra for the paper to be on one side, but now I'm worried because you said thermafiber, and somebody else said rigid fiberglass, and now I'm reading on Jon Risch's site that there should be space between the absorber and the wall, which I don't know how to do, and also that there is a problem if the fiberglass is too dense because it reflects the high frequencies instead of absorbing them.
What do I do?!
I could return the fiberglass for the other types, or just exchange it for 6" fiberglass to make those absorption traps, maybe. But that is just completely different from what I had in mind.
Soup, only you can save me! (Or Jon Risch...)

Ah, don't worry about it. If you've got 10-inch fiberglass, you've got plenty of padding. It'll work better if you can figure out how to space it a little from the wall -- a hanging bath towel works better hanging a few inches from the wall, but put up what you've got and live with it for a while.
Right now, you don't know, and you can't zero in on what you want until you do know, and you won't know until you put that stuff up and live with it for a while. You don't want to jump into some other guy's rut. Listen to the room before and after. Maybe put the stuff up with Harbor Freight spring clamps or drywall screws or something so you can fool around with putting it in and taking it out.
Do something, and it'll be better or worse. If it's better, enjoy it, and if it's worse just put it back the way it was and try something else some day. You'll spill some money but not nearly as much as some of us have.
Live.
