Tint is pretty easy..I did it myself- front and rear door except rear windshield.
I used bluish silver(?) tone metallic tint which goes with my car(satin silver)
can't remeber the price ...but it was about 50bucks..
I heard titanium lasts longer than regular and metallic.


all you need is good razor blade and sqeegee.. and there are many web site shows "how-to"
