If I install and synchronize the official Bitcoin wallet, can I backup/transfer it to another computer, so that when I install Bitcoin wallet on the other computer it doesn't have to spend so much time synchronizing?
Yes. Simplify go into the Bitcoin folder and copy every thing to the new computer. (Make sure you keep wallet.dat safe)
