Have a read of this;
http://wololo.net/cfw4dummies/ it'll help you get started.
I notice in your signature it says that you have the Apache exploit (though from your post, I take it that you've upgraded). Anywhoo, point is, if you've put homebrew on your Vita you already know enough about the PSP's file architecture. It's all rather simple, but I'll go over a few important things.
ms0:/ is the root.
ms0:/iso is where you put iso/cso
ms0:/psp/game is where you put homebrew and PSX games (eboots)
ms0:/psp/theme xmb themes go here in ptf format. If you have cxmb plugin you can also use ctf files for themes that completely change the layout and things.
ms0:/seplugins this folder contains plugins in prx format. You'll probably need a tutorial for this so I'll find a decent one, or write a quick one myself in a bit.
The rest of the files aren't all that important for the moment or are rather self explanatory.
If you need any other help when you get the console feel free to ask.

Ahh, awesome. Thanks for the info, Casavult.
