ask any gun store or cop and they'll point you in the right direction. I was similar (didn't know anybody w/ guns, not legal ones anyway lol), and ended up getting my CCP classIII i think (large capacity / conceal carry) in MA. Was a complete PITA but welllll worth it.
as far as trading guns, it depends. I can purchase a handgun from my neighbor if I want to here in FL, but if i go to a store I have to wait a day (*unless* i'm trading guns; if a gun goes from me towards the purchase, i can leave with handgun that day). PPL exploit the living hell out of this around here, with the "gun shows" (ie "come purchase guns w/o oversight flea market"). In MA, the rules were wayyyyy stricter, yet when i got my ccp and went to the store to buy my 1st gun, i was riding home with it that afternoon (rugerP345, fantastic firearm adn definitely my fav pistol i ever owned)
ALWAYS get and save paperwork, i have transfer papers to document every firearm that's ever come into / out of my possession (reasons for this CYA should be obvious)
but ya rules are very state-specific on guns, like in MA i had to take a course for weeks and pass test to buy a pistol (which i was allowed to carry), but in FL it's just an age thing (for buying one, not concealing it. You do need to permit here, like most any state, if you want to carry it)
what kind of shooting are you thinking of doing? I'd be damn sure about what my intent was before purchasing. I like big bangs, my ruger (.45) and mossberg(12G) were the most fun to shoot for sure, but neither was "practical". Was VERY fond of my modded-out keltec p11, couldn't recommend that thing enough for a fun pistol.
[plz note this is all relative to sporting and target, as you asked, and not defense. I cannot help nearly as much there, in that context i just see it as, basically, "a gun is a gun" lol]
[edit: i hope it goes w/o saying that having guns anywhere near drugs or intoxicated ppl is INCREDIBLY stupid.]
