Best Apps for Disabling Unnecessary Features (3g, Data, Bluetooth, Sync, & etc)

[supere36m3]

I am trying to save battery and speed up my phone. I know that I can in to setting to disable all these extra features, but I heard from someone that, "even though you disabled it, the phone will still continue to try to pick up these services, like 3G). Is there a app that will fully disable these features?

Also is there anyway up speeding up my phone. I have a Rooted T-Mobile MyTouch 3G w/ the CyanogenMod 4.2.13. I heard that there is a "10MB Hack", but I also heard that it will slow down your games. Is there any other way. Please let me know. Thank you.
