I don't mean to come across as rude, particularly to someone who is both a new player and new to this forum, but it sounds like you need to sit down and read the rules. Your questions are fairly simple and easily answered looking at the relevant parts of the rulebook. Hopefully these references can give you some assistance.

ccw and bolt pistol allow two attacks?
Sometimes. Have a look at the 'Weapons' section in the rulebook, specifically at Close Combat Weapons and Pistol Weapons. Also look in the Assault phase section under the Fight Sub-phase, 'Number of Attacks'.
If a unit has 2 weapons like a bolter and a bolt pistol can I shoot both of them if theyre in range (kill team)?
Sometimes, but usually not. Most models can fire only a single shooting weapon in the same phase. The 'Unit Types' section of the rulebook will tell you about some unit types which may fire more than one weapon in the same phase, as well as specific rules for specific units/models.
When do I use cover saves? Are they ever better than other saves? Do I make an extra roll for the cover save or is it in place of something else? Seems like they dont seem any better than regular saves.
Again the Shooting phase covers this. Specifically 'Types of Saving Throws'. If your models have decent armour or invulnerable saves already then generally cover saves won't be very helpful, unless they suffer Wounds from a weapon with low
AP.
Remember, this forum isn't a replacement for owning and referring to your own copy of the rulebook, but we're generally happy to help if there's something you don't understand, or if you need pointing in the right direction.
