For us older folks, I think the HID lights are almost a "must-have".
From what I can deduce (at least, no one has been able to convince me otherwise), the brembos aren't really necessary, or worth the money, unless you go to the track. Especially when considering the disadvantages, which (to me) are summer-only tires and no-spare tire.
I'd suggest doing what I did, and compromise on the gearing - go with 3.55s.
