What about an 'archer' fighter? They are defensive in an offensive manor. High Dex is good for AC bonus and to hit rolls. You can wear some armor. (Chain shirt, scale mail, buckler) Any extra strength is welcome if you ever pick up a composite longbow.
A level 1 Human Fighter would have what, 3 feats? I'd definetly take point blank, then precise shot for the first two. Then for your third you could do a number of things (depending on the level of min/maxing or roleplaying you want to do). Improved Initiative wouldn't be a bad idea. That plus your already big Dex bonus... you'll probably be going first in 98% of combat encounters. Which is great for an archer cause then you can ready an action to fire an arrow at any spellcaster trying to cast spells on their turn, trying to break their concentration. What a combo that would be, not only do you do damage, but you are counterspelling to. Or ready an action to be able to move away and fire at any advancing combatant if there are no spell casters. Later on when you get more feats, you could take finesse fighting which would be great with your already good Dex score for the bows. So if you ever find yourself in melee combat or unable to use ranged weapons, you always have a trusty rapier or something on hand.
Or you could be an elf and get that +2 Dex bonus, low light vision, proficiency with the longbow (although you get that for being a fighter don't you?) and immunities to sleep and such, some bonuses on search or listen checks. Oh and that ability to discovered magical secret doors by just walking past them. Although you lose a feat... which isn't THAT big of a deal. I mean, its one feat out of what? Like 20 or something you get as a fighter plus the normal ones. Its all about the roleplaying right?
How about a halberd fighter? Halberds don't have reach, but they can be set against a charge, give you a +2 to trip attempts and do a nice d10 damage. Its very effective espically if you coordinate with your party members. Trip up that enemy and have the rogue tumble by and give the ol' 'flanking proned sneak attack'. Mmm...
Along those lines is the flail. Instead of tripping maybe you would like to disarm people. Flails give you a +2 bonus to disarm attempts. Again there not reach. Plus they can be used to trip, although without any bonuses. How versatile can you be? Disarm, trip, smash, whatever.
Reach weapons like the ranseur. That gives you a +2 to disarm and has reach. Its a 2d4 too...
Or, you could go the Strength route. Maybe a Falchion. Its two handed so you get to add 1.5 Str to damage, and its crit range is 18-20. Grab Improved Crit later on (at level 8 cause you need a +8 BAB for the feat) and thats what? 15-20? Insane I tell you!!
Of course, theres always the good old net...
