The PS3 120 GB can not play PS2 games The 20 GB PS3 could play PS2 games and so could the 60 GB model that was released with it and those machines are called the first generation PS3 Models. The second Generation PS3 model were the 60 GB Model and the 80 GB model and while they could play the PS2 games it was based on Partially software-based PS2 emulation while the earlier models were Hardware-based PS2 emulation. These 1st and 2nd generation PS3 models all included 4 USB ports and also had Flash memory card readers. The 3rd generation of PS3 models had the 40 GB, the 80 GB, and the 160 GB Harddrives but only 2 USB ports and do not play PS2 games with backward compatibility. The fourth Generation of PS3s are the 120 GB and 250 GB PS3 slim model which do not play PS2 games with Backward Compatibility. All PS3 models play PlayStation 1 Games and do so through software emulation.

Nothing will make a PS3 that does not play PS2 games turn into one that does or it would be sold for people to purchase and widely available.
That depends on the size games and whether they have large files They also make a 320 GB that makes more sense if you are already worrying about your PS3 becoming filled and the games are not cheap.
The only difference besides price is the hard drive size.

The Slim PS3 not available in less than 120 GB and all PS3 have the capability of online play. One of the first PS3 a 20 GB model just did not have built in WiFi, but you could use an Ethernet cable or buy the 60 GB model with WiFi.
Yes and no. Only on the ps3 60 gb, and maybe a 80 gb. All 60 gigs are backwards compatible. Only one 80 gig.
No you can delete and download them again. I purchased a 320 GB PS3 and have it almost filled with purchases and free games from Playstation Plus, but was able to re download all the games from my earlier PS3 120 GB purchases Games can not be downloaded using your USB port in either direction
