Remember that taking Exotic weapon prof. requires that you have a BAB of at least +1 so you can't take it at 1st lv if you start as a rogue. Start off with Combat Reflexes instead and take EWP at your 1st fighter lv. I recomend being a Dwarf, the 20' move is kind of a pain, but as long as you aren't wearing heavier armor you will stay that fast. Having the reach weapon also kind of negates some of that slow movement. But I think the extra con will be a life saver since you are going to be relying on rogue levels for most of your life. the bonus to save vs spells and poion helps make up for the rogues weak saves. I also think going the strength route could be fun esp if you pick up the Knockdown feat. with a decent strength almost all of your aoo's and attacks will have a chance of knocking a foe to the ground.
