I'm out of touch with new gear, but you may want to stop in at Fisherman's HQ or down here Tackle direct and talk with some guys. TFO's are great rods, and I have a couple but depends on what you want to throw and the specific rod w.r.t. distance.
10 and 10'6" will both likely get you further than your 9'.
As to the 4500, look at the capacity and see if that fits for you. 5 oz lighter will make casting sessions more comfortable, but neither reel is going to increase your biceps much
