Root, Superuser and Busybox

[Tynictansol]

I'm booting off NAND via the instructions here and have been having a noob of a time getting applications requiring root access to function, with Titanium being the main app I want so I can more easily transition between installations for testing purposes. I've attempted to download Busybox, however it fails installing due to inability to get root access, as well. I have XP Windows with ADB Drivers installed and I can get around a little bit in Droid Explorer. I don't get prompts when opening applications which require root, just them saying they failed to get access. I have USB Debugging enabled, if that matters at all. I've done some digging in the various threads here though perhaps I don't know the terminology I should be looking for. Superuser, busybox, root don't land results which have been helpful to me, unfortunately, and all discussions of the topic in forums not specific to the TP2 seem to bear only cursory relevancy to it. I have a RHOD400 type device.

Thanks in advance for any and all help provided and if there is, in fact, a thread or post which covers this in a way I might be able to follow just pointing me in that direction would be most appreciated.
