i swear to god im starting to think its the same person or group of people starting all these threads just to **** with our heads. to answer your questions:
1) use the search function. seriously it works. but to speed things up, check this out

ftping games to your ps3 is really simple. there are plenty of apps on this site that will do that. OpenPS3FTP ive heard good things about. i used blackb0x before I picked up an external. id recommend picking up one. theyre not too expensive.
2) no and yes. i heard some 3.56 games work with spoofing and others merely need to have some files swapped. for 3.60+ compiled games, the only ones that work have had patches released by the publisher at a lower firmware. the ones that haven't are unplayable for the foreseeable future. read the modding, online, and rebug sections for more detailed explanations.
3) you're fine on 3.55 and below. just make sure you have the auto download feature turned off in xmb.
as a general rule of thumb, its a good idea to read up on threads here, especially when you haven't ran into any problems yet. even when you do, its still a good idea to search for a thread where someone ran into the same problem, which is frequently the case. starting a thread is a last resort for when solutions no longer work or you can't find a thread that answers your question. best regards.
