I've got a new bike that's great, now I need to put a couple bags on it for some distance rides.

I think I would like an expandable seat bag and either a handlebar bag or a bag that straps to the top rail and stem tube(?). Does a handlebar bag hang on the front or rear side of the handlebars? It looks like it would interfere with the cableing on the front side.

I want to carry a patch kit, spare tube, some sort of pump, some sort of multi tool, a wallet, cell phone, iPod, water and gatoraid (hydration pack maybe), a snack or two, and a 9mm compact pistol. Any other essentials that I should carry?

I was looking on a site call REI.com. They had a lot of stuff but I know there are a LOT more sites out there. Any suggestions of sites with reasonable prices and good customer service? Thanks in advance for any help.
