Multiple Problems
As far as the steering goes, have you checked your fluid level? Check that, if full then you may need to bleed the power steering system. To do so is fairly easy- Put the front of the car on jackstands so the front wheels are suspended, start the engine, quickly turn the steering lock to lock. Do not keep the steering on lock. It's bad for the pump especially when low on fluid. Do this several times and then check your fluid. If it's low then simply refill and turn lock to lock several more times and keep checking.
Check to see if you have any leaks in the p/s system as well...
