How many audio CD's can I burn?

Question

So, I took the plunge yesterday and bought my first music store tracks. Now have a few questions (I suppose logically I should have looked for the answers first but I just wanted to try it anyway
Most of all I'd like to know, is there a restriction on the number of audio CD's I can burn? I've read 7 in a couple of posts but can find absolutely zilch in Apple's support about this. Must say, I find it a bit of a cheek if there is a restriction. It's my music now, afterall !!! I just hope the whole point of not allowing you to burn from Toast anymore, but only from iTunes is to remove this need to limit burning?
Which leads me to my next question; this thing about only burning from iTunes now... is that a restriction set by Toast or by Quicktime? Or both? Because I read somewhere that QT7 prevents you from burning. Somewhere else I read you can still burn using Toast 6.0.1.
And finally a question about quality. This is something I've been struggling with for a long time and my library has become chaos as far as encoding is concerned. I just can't decide. To me 192 bit MP3 sounds fine, as does 128 bit AAC (Music Store). But everywhere I read people seem obsessed with seemingly huge bitrates always rubbishing these so called "high-quality" settings. So being the gullable person I am I've started believing too much of what I've read and become paranoid that 128 bit AAC just doesn't cut it.
Thing is, for a long time I went along with the old addage "if it sounds good for you..." but I'd like to start taking my powerbook out with me DJ-ing (private parties, small venues) as I'm fed up of lugging vinyl about, not to mention people who don't have record players anymore . But are music store files gonna sound bad over a small/med sized sound-system? Or am I just being scared by a few audiophiles who hang out in recording studios 12 hours a day and for all their trained hearing have forgotten what the layman hears (or doesn't hear)?!? Because if the answer really is "forget it, it'll sound awfull" then I really need to question the point of buying from the music store.
Thanks in advance for your opinions...

Rich,
Sounds like you have your answer as far as the number of times you can burn a playlist with protected music in it. Keep in mind that if you alter the playlist you can get another 7 burns in.
By the way, just because you buy a CD or "Tune" doesn't make it "yours." How would you feel if you produced a track, went through a copyright process, and everyone who paid $1 for it had legal rights to it? Yes you own a copy of others music but it doesn't give you the right to mass produce it and/or distribute or sell it. DJ's like us are always skirting the line between copyright infringement and remix / alteration rights. I mean we get paid for playing other people's music right? Copyrights are there to protect artists against that scenario exactly. OK (stepping down from my soap box now)
Bitrate / Quality - of course through most systems 192 MP3 or 128 AAC will do just fine. But, just how large are these parties? If they truly are small house parties say one room up to 100 people, I'd say you're fine. But, when you play that same track on a full on sound system in, say a club or something (1000 people or so) with 2-5000 watts or more behind it, you will hear all the fuzz, noise, pops, etc. In the end it really is a personal decision, what's suitable quality to your ears? The vinyl sounds better doesn't it?
Just my opinion...Hope it helps.
