Shake in the steering wheel

[Powerzen2002]

Here is another quickie question. I know the general facts,
but need more specifics. I only have this car for about 6 months now. So ... if anyone has any clue on the following:

-My steering wheel shakes at 55-75 MPH
-I know for fact one of my rims is bent, but i had it balanced
and put in the rear.
-My front struts DO need replace'ing, but they are not that
bad, just giving me a little bumpy ride.
-When I press on the brakes at above 55 MPH, the wheel
Shakes EVEN MORE - but not crazily, just a little more shake
than it would normally.
-On a side note, i just replaced my TC Bushings for safe
measures. Plus, just had my rear brakes done, had roders
 cut.  No problems there.

From all this, I can tell my front roders probably need replacing? But could the bad struts also cause some jitter in the wheel? Could the slightly bent rim even after balancing cause some problem although in the rear now?

What else should I see for wheel shaking? (Checked the tie rods and bushings, they are fine)

Thank YOU!
