It can be a little tricky to get a spring compressor on/off the H&R springs, just keep an eye out for it.
The rear suspension bolts can be very tricky. Use lots of WD-40 and have a torch handy for some heat.
Are you replacing the upper strut mounts too? Might be a good idea. Might want to get good strut dust boots, stock ones are usually worn out.
Also consider replacing front LCA bushings, pedders has a set of urethane bushings for $100 ish, and at the minimum I'd replace all your swaybar link bushings, again pedders has those and they're not too expensive.
