Funny thing, I'm actually playing one of these - Speed of Thought, Psionic Charge, Up the Walls. Next, add in Boots of Springing and Striding - if they stack with Speed of Thought (not sure there), you'll have a base speed of 80. Now, you don't need to worry about getting anywhere. Throw in maxed-out tumble, maxed-out jump, and you can duplicate D-door without the need to actually have the power.
It's not really that useful in combat, though - I think I've actually used it once, and then only because I wasn't remembering to use my Tumble. I've never used Psionic Charge, either. It's more of a utility ability than anything else - don't need to worry about rope or anything like it, as long as the drop off is less than 4x movement.
Now, if you add in the Spring Attack chain... you've suddenly got some options. You become the expert of charging in, plinking them for a piddly amount of damage, and getting out. You could also be a useful utility person - run in, give potion, run out. Or, run in, grab nearly dead party member, run out. Just don't expect to be a tank. More like a guerilla fighter. Maybe multiclass later, get some levels of rogue for sneak attack purposes...
Also, as others have suggested, try seeing whether your DM would grant you attack/damage bonuses for the fact that you're doing something extremely unexpected, as well as striking from higher ground and all that stuff. Might not work, but could be worth a shot.
