You're always best to go shorter. Too long makes it hard to pull and hold, sometimes impossible (although too short can make it hard to shoot).
Your best bet is to drive the long haul to the pro-shop and get measured. It will save you many problems in the long run. Short of that buy a cheap fiberglass bow and put a measuring stick on it. Or make a loose fist and draw a yard stick over it to the corner of your mouth. Or find a friend with an old bow they wouldn't mind adjusting and try it at different lengths.
Another thing about the pro-shop is that they probably have somewhere you can shoot the bows in order to try them before you buy them. And a pro-shop will save you in figuring out which arrows you need.
29" seems to be the average draw length. I just measured myself your way and was real close to my draw length. But it seems that long/short fingers would mess with that way.
$85 for a compound is probably not quality. It may have been good back in its day but it's probably so out of date that it isn't now. Figure about $200 for a good starter level hunting compound. The $85 one would get you started but judging from the <$100 bows I've seen (and the one I started with) it wouldn't be suitable for hunting.
I'm desperately trying to talk a friend into buying a better bow. His is the same quality as my $90 bow (in fact I think his is a Bear). He can't hit the broadside of a barn with it and it doesn't have the energy to go through the broadside of a deer. My old bow has the same problems.
Any bow you buy is stripped down. They may have a "kit" but that's on top of the price of the bare bow. Things I'd get, release, sight, rest, string loop, stabilizer, string silencers, teflon cable slide, arm guard. The list could go on and on. Even if the "kit" gives you some quality items at a good price you'll still need to add some other things.
What you get depends on how you shoot and the arrows you decide on.
Welcome to the world of nickle and diming yourself to death.
