I haven't seen a guide for the TvC stick, but a general guide will work. Note that if you mod it like I did you will lose the ability for it to work as a Wii classic controller, it will be supported as a Gamecube controller though.
I used an MC Cthulu with an RJ45 port. This allowed me to make detachable cables to easily switch between system. You can find a guide on using a MC Cthulu in this setup at the Shoruken forum's which are apparently down today.
I used a 360 Brawlpad along with an IMP v2 to allow a single USB cable that auto switches between 360 and PS3/PC mode.
There are a few limitations when you do this, you will lose turbo functionality along with the LS/DP/RS functionality unless you wire these directly to the brawlpad. These functions will not work with anything besides the 360.
You will be required to solder some wires to the brawlpad along with MC Cthulu and the IMP. If you aren't up to the task of Solder I would locate someone who is able to, none of the points are that tricky, but they aren't for a first time solderer.
Finally, if you don't already have a TvC stick, I don't recommend modding one. For the price of the TvC stick and a brawlpad you'll be close to the price of a 360 stick. This will allow you to more easily perform the mod as you'll cut out half of the work. If you have a 360 TE stick, there is a mod called the Kitty that is a literal drop in mod that require no solder. If want to go 360/PS3 it's only about five minutes worth of work. The Kitty also supports the RJ45 connector for all the additional console support, but it's a little more work since you'll have to mod the case a little to add the RJ45 connector.
Here is a picture of the inside of the stick:
And here is a picture of the cables I made, ignore the PS2->Wii cables in the background. I tried them and they don't work with this mod:
