[Placebo]

I've coded in C and C++ before, so learning Pawn isn't a problem, but there's a few things I don't understand..

1. Do I need object streamers only when I have over 400 objects? or would it be better for players if i use one, anyway?
2. Do I need a vehicle streamer only when I have over 700 vehicles? or would my script run more efficient if I used one anyway?
3. Is a thread like this already posted somewhere, where I can reference known SA-MP bugs, things I can and can't do with Pawn/SA-MP?

Thanks.
