You should definitely use the Unofficial Tweak Pack to remove the most questionable elements of TSLRCM. Some other suggestions from my usual suspects list:
Backdrop Improvements
HD Cockpit Skyboxes (despite violating my "HD" rule)
Head Model Fixes
High Quality Blasters
Luxa Hair Fix (make sure to use the hotpants option!)
Realistic Nar Shaddaa Skybox
Realistic Visual Effects
Telos Citadel Station Skybox
Since I seem to recall you not always playing in widescreen, these are optional I guess:
Improved Widescreen Experience (stretched UI fix)
Main Menu Fix for Widescreen
Probably a good idea. Not least because, unlike K1, TSL is fundamentally broken in ways that are not easily fixed beyond the remedial work TSLRCM has already performed.
