1. Your firmware for cfw must be 3.55 below on your 60gb ps3.
2. I believe your trophies automatically sync when you go online, so if it's transferring you want then I'd probably suggest do a data transfer.
3. You can repair a blu ray drive very easily on the ps3 it takes around 45 minutes, patience and around £30 to buy the deck and lens together, it's definitely worth investing.
Hope this is of help
