control arm bushings and a arms
control arm bushings and a arms my bushings in my upper control are just about gone. can you just replace them any sugestions on bushings or what??? is it a pain in the *** to do or not??? 
AFA replacing the bushings in your arms, the best solution would be to replace them with Moog Problem solver bushings, TRW, or even AC Delco (which I refrain from since they're are a little more expensive, but not too much more). The old ones need to be pressed out and the new ones pressed in by an arbour press (very carefully), or you could use the torch method (stinky, takes long, and is messy as well). A shop can certainly do it, however prices will depend on shop.
AFA tubular a-arms, it depends on what you're doing, however I say that poly bushings aren't the way to go because they'll introduce additional bind that isn't desired in those locations in the first place.
For what I do (AX and open track RR) the tubular arms are mostly useless. I have had some and they didn't necessarily save enough unsprung weight on either upper and/or lower arms. for the upper, there is very little loads to begin with. For the lower, the type of tubular arms that I have tried have each broke (the lower ones, even on the street).
Really, it's up to you, however the stock upper and lowers aren't really too much terribly heavier than most of the aftermarket items, and they withstand some brute strength pretty well. I say for a street car, get some replacement rubber bushings, have them pressed in, and you'll notice how much the ride is refreshed.

I believe you are asking about the upper front arms.
You can see the upper arm on the right. Once the two short bolts are removed the arm comes out of the bracket. From there its easy access to the bushings. If you have never removed bushings its not hard but takes proper tools to do it. A very large vice and some very large sockets are needed. You also need to fit some pieces into the arm to keep it from collapsing while pressing the bushings in or out.
Here is a bushing being pressed in. There are 2 sections of pipe around the bushing in the arm to support the arm from collapse. The large sockets just act as a receptacle on the bottom and a mandrel for pressing on the top.
