Did you buy the car this way or did it recently happen?
You should be able to check these reasonably at home:
On a level surface measure the distance from the bottoms of the front
control arms to the ground. If you get a big difference from one side to the other, one of the
control arms is bent. (Its hard to bend a stock control arm. Usually the ball joint goes first.)
Find a spot that you can as accurate as possible measure from the lower control arm to the upper spring perch on each side. This will tell you if your springs have sagged from one side to the other.
Disconnect your sway bar end links to the
control arms. Bounce the front up and down a few times to let the car settle to its spot without the sway bar. If the car levels out its the sway bar bushings or end links.
There is really no good way to check the shocks without pulling each side apart. I've been trying to think of a safe way to do it and I haven't been able to come up with one.
If the car was hit hard enough to bend the K-member I personally wouldn't spend any money on the car. There will be signs all throughout the sheet metal that the car was hit fairly hard. Once metal is bent its near impossible to get it back to its original shape. When I get home I'll take some pics of stuff to look at one the frame but I think your issue is probably something else.
