I would guess yes the mirrors are wired up for signals, I say this because it worked on my 06 f-150 however you will have to buy 2 new mirrors with the signal lights in them.
For the keypad I would guess yes its wired for it as well but you will have the buy the window sill trim along with the keypad, only thing to chance would be the computer that controls the keyless entry, how would you get a code and get it to work with the existing computer on the truck.
I have seen and thought about buying the switchblade key, it looks pretty cool, ,my only drawback is your buying it from Taiwan, I have bought many things on Ebay but never out of country, would be leery of sending money that way with no real recourse if the deal fell through. One thing I am looking into is the Fusion key which has the door fobs built into the key head, no extra keychain, It worked perfect for my 06 f-150 but since I no longer own it I cant test it out on the Expy.
