My car has 55,000 miles on it, i am the second owner, and sometimes beat on it. With these mods, what would i need to do to my transaxle or anything else to easily handle an occasional beating?
Your SSEi has a HD tranny, someone correct me if I'm wrong. That level of mods you will be fine with a shift kit. Get the street/strip kit. I'm still running a stock tranny, other then the street/strip kit, but I'm now looking in to upgrading before I go much further.

Stock rating for the 4t65E-HD is 280 ft/lb. The car makes that stock. ANY modification even a 3.4 pulley that adds 50 ft/lb'* puts the trans at risk. That being said most transaxles in good shape last for quite a while up to about 280-300 whp at which time the input shaft is a real concern especially with large rims and good traction.

How much effort is involved in changing the input shaft and torque converter? Does the engine need to be removed? Is this a weekend project, or longer?

The transaxle needs to be taken apart down to the input shaft. This includes removing the channel plate, valve body, gear set etc... This is not something a layperson should attempt and should be done by a competant and trained transaxle repair tech.
