A bit of help please?

I've been playing PS2 for a few hours now and have a few questions I can't seem to find here on PSU. These will probably be some very easy to answer, lol, but for the life of me can't seem to find the answers to these.

1.) I know that big vehicle you can spawn on (don't remember the name of it) can supply you with ammo, but how else can I replenish ammo in the game? I seem to always run out of ammo very quickly.

2.) How can I find a squad of my liking in MY area? And not random.

3.) Is it possible to zoom in and out of the mini map?

4.) Most importantly, how do I get new weapons and other gear such as armor? Do I really have to pay with real money in order to get armor? Please don't say it's true....

Thanks for the help!
