Clean Up Sprint Stock ROM

[doireallyhavetodothis]

I prefer to use the stock rom as it's the only one that allows me to stream music from tuned.mobi. I have the stock rom and used a program to adjust the page pool BUT how can I take out the automatically installed Live Search and SprintTV which are both outdated in the stock? I tried to install the updated Live but it didn't delete the old version and instead just installed Bing. I don't want SprintTV as I don't use it. I know there is a cleanup .CAB on here but I'd prefer to make the change permanent so I don't have to run some program each time after a reset.

I realize there are ways to customize a rom to pre-load programs but I'm not clear on how to do that and if it's at all possible with Sprint's stock rom.
