Looks good. I only see a few issues:
1. Why is touch AC 14? All I see affecting this would be Dex and Dodge. Dex brings you to 13, and Dodge isn't factored into your regular AC and would only apply to one opponent anyway. The Misc bonus seems to be the enhancement bonus from the +1 breastplate, and that doesn't apply to touch.
2. I believe your attack bonus with longsword should be +9 instead of +8 as listed. +4 BAB, +3 Str, +1 enhancement, +1 Weapon Focus.
3. I think your damage should be 1d8+6: +3 Str, +2 Weapon specialization, +1 enhancement.
4. You're missing a feat

You get 2 standard feats at levels one and three, 3 fighter feats at levels one, two, and four, and you get 1 extra feat for being human. This comes out to a total of 6 feats, while you just have 5 feats listed. Your fourth level fighter feat is taken (Weapon Specialization), so the feat left is the standard one you'd get at 3rd level.
5. You forgot your human skill points as well. You should get 4 x 7 = 28 skill points, so you've got 7 more skill points to spend.
6. You might want to notate your armor check penalty to climb, jump, tumble, and swim. It seems to be -4 (-3 breastplate, -1 mwk heavy shield) for most of those and -8 for swim.

I also like your description. If the three of you want to work out how your characters met and some history or what not, that's cool. It also could be that you only met recently. You can assume a standard fantasy setting and either use made-up places or stuff that's from Greyhawk, like in the implied setting in the PHB.
For the start of the adventure, you'll be traveling through a rural countryside where the closest real cities are many days away.
