Question on buying tix....?

[HTown2ATX]

I'm interested in getting some tix for some games this year. Namely the Steelers game (for me and my Steeler fan dad), the home Titans game and maybe on other home game...doesn't matter against who..

Anyway, I've always lucked into my tickets from family when I was married, my lawyer, etc..

This is my first time buying them. Is stubhub.com the best place to go (that is where I have initially been looking)? I saw decent prices but all mainly in the nosebleeds. Is there anywhere to look that still has decent prices but not quite so nosebleed?

Also, on stub hub I didn't see parking passes? Are they on there too or how do I get those?

Thanks for any help.
