That's not a bad price for the lot, but the rears are useless to you. You would need to ask them for a quote on the Fr and Rr shocks plus Fr springs and get a price on resetting your rear springs.
I don't see anything wrong with using Monroes, have used them myself and they do what is expected of them.
You can try these guys for the Fr Springs

As to bushes, are you considering the plastic type or the original rubber ones? Personally I wouldn't touch those plastic ones but to each his own. I recently put a new set of rubber ones in the front of my AU XR6 and replaced the ball joints, rides really well. The main thing I did was to replace the upper control arms with BA ones and used the brackets from an XR6, longer bolts and a thick spacer/s that seems to help.
