The various brands is all about what you're looking for. Che's will do the job just fine, but probably won't have that X factor that makes them a little bit better than everything else. 3.0 (corky's) is the next step, more costly, but being handmade by nothing short of expert craftsmen who know their Spyders gives them the potential to be better. They also provide all the Spyder-specific bracing you could need, Che does not. Tom's is the next step. The Gucci of bracing, if you will. Very strong, very beautiful, very expensive. Probably more than is necessary for the average driver, but some people just have to have the "best". I would recommend Che's or 3.0 from what I believe you will need.
As for the order..there is a little variance here..but
1. breastplate or MSMB
2. Front strut tower brace.
3. rear lower member brace
4. front lower member brace
5. rear strut tower brace
6. anything else you can think of
If you were to even get to say...3 or 4, you'd be pretty set, but every little bit helps.
