track oriented suspension

Right now I'm on the stock suspension and while actually not bad, its basically shot at this point. So I'm going to piece together some suspension bits for the winter. Here is where I am, please advise if I should do something different. Also note this is a low budget car, so I won't be doing pss9s, kws, or motons.

H&R springs with Bilstein HD sports (B8s)
New stock strut mounts
extra slotting on front strut towers
Megan racing rear toe links (adj)
replace with stock any bad track rods or control arms.

So here are my questions:

1. megan racing says their toe links are for 987s or 996s. But other brands use the same part number for all models, so I'm assuming they are interchangeable?

2. Should I do anything with the tie rod ends?

3. What sort of camber and toe should I be looking for here? Not 100% track, but probably 75% track, 25% street. I'm hoping to avoid buying GT3 coffin arms.

4. Anything else I'm missing?

5. Those rear bars that tie together the rear suspension castings. Useless or no (technobrace is one example)?

Thanks very much
