1. Well, firstly, you must have a PSP that has official Sony FW on it. Custom FW was made by a talented group of hackers, and allows you to do all sorts of wonderful (albeit, mostly pirate-like) things on your PSP, replacing Sony's official FW. This can be done by quite a few methods, the currently preferred method uses a softmodded battery to install CFW (Pandora Battery).
2. Well, a ripped ISO you can usually find anywhere on the internets. If you obtain one, and have CFW, you can simply copy it over to your memstick and run it on your PSP. Also, with an ISO, you can use various programs on a PC to modify the contents of the ISO (game). This is useful for trimming down the ISO size by removing useless content of the ripped ISO and you can even compress it into a playable file, a CSO (Compressed ISO). I don't have too much experience with the PS3 or the PSStore, but I'm almost certain that you can't carry your purchased games around as widely as you can with an ISO. As far as difference of content, there is none. The games are exactly the same, except you'll be paying for a legit copy on the PSStore and supporting the wonderful game development team behind it.
3. Almost all of them are usually EBOOT files, the same type that ripped PSP ISOs, and ripped PS1 games for the PSP are.
4. If I remember this correctly (I'm a little hazy
), the OFFICIAL emulator requires you to buy a title from the PSStore and then transfer it over to the PSP using remote play or something like that. CFW allows you to find any PS1 ISO (even games that aren't on the PSStore, basically any PS1 game ever ripped from back in the day) and convert it with a program into an EBOOT, so that your PSP can play it. The PSP has near perfect PS1 emulation with most games.
5. Answered above. The only thing you would need to install would be the program to convert a PS1 ISO into a PSP EBOOT.
6. Umm... iono. Shoot some more questions this way if anything pops up!
