Help fix my mess of dashboards

Here's what I did to get me to where I'm at now. I followed this guide to softmod and install Evox with Agent Under Fire.

I then used AID disc to install Unleashx on E drive. Then I installed XBMC as a App. What it does is boot straight to Evox and if I want to get to Unleashx I have to go to Launch menu>Apps>Itools>dashboards>Unleashx. Which is inconvenient and is not what I originally wanted. I wanted (at the time) to replace Evox with Unleashx and have it boot first. Now After playing with XBMC I want it to be my default dash.

So what I'm asking is how do I remove Evox and Unleashx and have XBMC as my default dash and have Unleashx as app or secondary dash?

I was thinking of following this guide to restore my Microsoft Dashboard to it's Retail State.

Then use this guide to softmod again.

Then from this point I have no idea how to install XBMC as the default dash.
Maybe there is a easy way to do this without having to go through all that. But this is all I could come up with on my own. I was going to use the stable build XBMC from http://217.118.215.116/ if it helps any.
