Questions 2 and 3

The gist (according to them) is that Ti hardware is just as strong as the steel. Al hardware is not as strong and hence unsafe for critical applications (such as your brakes' center pivot!). Of course, SRP might be a little biased in the matter...

Ti is equal (or nearly so0 to steel in nearly all aspects, but weighs 1/2 as much. Aluminum has about 1/3 the strength in any application (compared to steel and TI), but weighs 1/3 as much. Combine steel and aluminum, and you get a strong galvanic cell. Ti and steel makes for a weaker cell, but a possible place for corrosion just the same.

The use of zinc chromate paste can aleaviate some of the galvanic issues with aluminum. It's a fairly common application around boats. Eventually the zinc gets used up and then the aluminum starts to corrode.
