I think you are lost. You are jailbroken now right?
I personally would use pkgbackup (from Cydia) and back everything up, update to 4.3.3 via iTunes, and jailbreak with redsnow and then use pkgbackup to restore all your hack stuff.
The most reliable (and most popular) tools would probably be;
-Spirit (older softwares, I think)
-Jailbreakme.com (older softwares)
(how about that Leigh? )
