Getting ready to pull trigger on build kit - got questions - any help appreciated

[Fman]

Here is what I am planning on ordering in near future:

Mk4
Coyote engine w/TK0600 trans
IRS suspension/rear end
Leather seats
Power steering kit
17" wheels
Going with base disc brake kit (No wildwood)
Wiper kit (to pass CA inspection for SBC-100, prob will never use)
Heater
Adding heated seats
Passenger side rollbar
Floor mats
Sun visor
Wind wings

Anything else someone would recommend?

Few questions I have...

Power brakes? What are guys doing to add power brakes? is it necessary or is the wildwood pedal box adequate?
Roll bars? Someone mentioned some guys cut them down 1"? different vendor that sells a shorter roll bar?
For guys in CA, do you need wipers to pass the inspection? I would really not like to buy them but also dont want to fail because they were never installed.
Where should I buy my engine/trans? Is it best to go with Factory Five?

Thanks for any feedback...
