Should I start giving my 7 month old Gerber Puffs/other finger foods?

My son just turned 7 months (on the 26th) and he has 4 teeth, the bottom two are almost all the way in and he has two on top (no the center ones though) that you can see and feel but they still need to grow in a little better. Anyways, he is always grabbing at my plate and wanting food whenever I eat, he smacks his lips for food, lol...I was thinking about setting him up in his high chair with maybe some gerber puffs, cooked carrots, bananas, etc etc and let im try to learn to feed himself and keep him occupied for a little bit....I am afraid he might choke though! Hes got teeth, and I know they ay those things dissolve but Im still a little nervous....Do you think I should let him? I think he is ready because he is VERY interested with foods right now but I just dont want him choking....
