nope, you only need metal gear solid portable ops plus (real bummer to spell) i only have mgspo+ and its ok for me.
You play as big boss, the father (genetic twin) of solid, liquid, and solidus snake. It also explains how the patriots came to be. this side story is continued in metal gear portable ops and the topic is closed up in mgs4.
Yes, The games are Metal Gear Solid: Portable Ops and Metal Gear solid: Portable Ops 2, There is also a card themed MGS for the PSP which wasn't really good, But was an essential for Die Hard collectors, If you eBay them, You may be able to find them pretty cheap.
Yes and no. It does not contain the original MGS portable ops, and you can take soldiers from the original and add them to it, but you can play it without the original game.
In most of the games you play as Solid Snake. Hence the name Metal Gear Solid. You dont play as Solid Snake though, in MGS3 MPO and MPO+. Also Metal Gear Acid 1 and 2 for PSP
Play Infinity Mode on harder difficulties. Extreme provides the best soldiers and equipment.
Konami has said that in an upcoming expansion pack to Metal Gear Online you will be able to play as Raiden
Very unlikely, but on PS3, there's a lot more fun Metal Gear Solid series;better than Metal Gear Solid:Peace Walker.
nothing
Yes you can, it is on MGO.Metal Gear Online for Metal Gear Solid 4 which is on the PS3™ System."while in Metal Gear Online, the Metal Gear Solid 4 version of Raiden appears as a unique player character."

no, but Metal gear solid 4 can be played online. MGS3 had it too, but it was for PS2 so the online got shut down.
No, you cannot play split screen at all. You can play online though, in MGO (Metal Gear Online).
