Very nice, but flawed.

For question four, you've left out alot of stuff. The things you've mentioned have very little use without some of the following:
Flash2, Flash3, iDstorage, Initail Program Loader (IPL), ISOFS, FatMS, iRda[x], mscm0, mscm[x], UMD00, UMD01, UMD[x], host0, WAD, lflash, prfat0, msstor0p0, msstor0p1, flashfat[x].
I know this is meant to be simple, but it's a bit of a kick in the bum if someone is lead to believe that the PSP works so simply.

Also, for question five, 1.50 does not accept homebrew. Infact, 1.50 was the first one to block unsigned code. Swaploit and Kxploit were the only things that let 1.50 be so open.
