I'm getting absolutely reamed.
Haven't even got a clue how to setup the guns at the start of the game.
I've got no instructions as it was a steam download.
Don't try and buy a gun every round, particularly on the larger public servers you can afford to spend a couple rounds saving money. Put faith in your trusty standard pistol and if you follow the path most of your teammates take more often than not you'll run across a dead body and pick up their gun.
Once you have about $3500+ it's usually a safe bet to press the 'Autobuy' option (on the right side of the buy screen). This will give you an M4 as a Counter-terrorist or AK as a Terrorist - these are 2 of the most used weapons in the game so get used to using them. You may want to supplement your equipment with a flash or smoke grenade, but observe how others use them (i.e. don't smoke infront of YOUR awpers (snipers) and don't flash infront of YOUR teammates).
Aside from an M4 or AK, 2 other frequently used and useful weapons are the MP5 sub-machine gun which is good for closer gunfights and is often bought when someone needs a gun but only has about $2000. Another is the AWP sniper rifle, at $4750 you won't be able to afford it much if you're a frequent dier, and will take a while to become good at, but it can be an awesome gun.
BTW, I'm basing this on normal priced servers, dynamic price servers (which I don't go on and if I'm correct are few and far between) have constantly varying prices so buying weapons, kevlar, grenades will take a bit of time.
Oh, and if you're on Dust2 and a Terrorist, if you can't buy quickly to begin with, make sure you're not in line with the middle double doors before you bring up the 'buy' screen - otherwise you'll be an easy pick for Counter-terrorist snipers.
