I do not have any football gloves and thus by the rules of mathematical logic the question is not posed.
Two good brands of football gloves are Under Armour and Cutters.
there are lots of different football gloves for center/linemen heres a link to a page with football gloves make sure to scroll down that's were the lineman gloves are i would personally recommend the nfl equipment smash football gloves (one of my teammates had this and the grip was nice) (however i do play wide receiver and corner back so i am not an expert, but i do know a lot about football equipment) a lot of centers also wear half finger gloves which are on this page http://www.weplaysports.com/football/gloves/
It depends what type of league. Yes, it seems to help for some people. Like me I play travel ball. I use baseball gloves, but i can't see why you can't use football gloves. It may help you and it may not. It depends how YOU like it! :)

Cutters
some wear no gloves i play long snapper and wear receiver gloves (because i also play wide receiver and DB) and they work fine for me there are no gloves just for long snapping just wear whatever you like

There are many sporting goods retailers that offer deals on football equipment. A store such as Big 5 may sell a variety of football gloves and there are also deals online.
