Hey i'm new to this site, but it's cool and quite helpful, good job!

I'm a new mapper but i can do some things =]
But i have started a new surf map and i was wondering a few things, and if they could be made into a tutorial i would be really grateful

I was wondering how to make a spawn point for Terrorists and Counter-Terrorists to stop them spawning with guns, just so they have knives. Also, i have made a jail for my map but i want to make a button to kill everyone in it, so could someone possibly help me on that? And also, i want to make some weapon spawners instead of making loads of weapons, plus how to make weapons float in mid air instead of falling to the ground, i don't really understand any fancy stuff i'm afraid, sorry

There is loads of other things i would request but i'll just stick with these because some are probably really obvious so i'll just not mention them hehe.
Thanks in advance for any help you can give me!
