Hey. I Just Recently Picked Up A 8GB iTouch With Firmware 1.1.4

I Successfully Jailbroken It With ZiPhone And Installed:

During The Testing Out New Apps, I Install And Uninstall A Bunch Of Stuff
Once In A While It Freezes
Now Im Thinking To Restore My iTouch And Re-Jailbreaking It

Is There Anything You Should Recommened Me Doing:
Before JailBreaking It?
After JailBreaking It?
What To Install?

Can Ya Guys Please Tell Me What I Should Install?
Im Planning To Re-Install These:

When Im Playing Certain Games It Moves Slow, is That Normal?

Thanks In Advance
