manhours for front suspension rebuild?

ok, I priced all the pieces that come in the PST kit on rock auto.
I looked at both the best "Ray Bestos Pro" pieces and the cheep moog pieces, total comes from 534 to 320 so I could be saving or spending about 100 more than the 439 for the PST kit.

So now the question is: what parts are maybe worth spending extra on and getting the potentially higher quality parts for? are should I or should I not spend extra for the Ray Bestos parts?...

also I'm not sure about how many of the following I need
lower control arm bushings
outer tie rod ends
inner tie rod ends

I think its 2 of each of these, is that right?
