I'm fairly new to both Joomla and iJoomla. I have iJoomla Magazine installed, and I'm ready to incorporate the site design I've already created in Photoshop. I'm a little confused though. Do I make the CSS changes via Joomla or iJoomla? I would like to find a sandbox theme (a neutral template with very little styling but enough hooks to add the necessary styles and elements) that I can work on to make the design happen.

I could use a little advise on where to start, and where to find a very neutral template that I can use as a blank canvas.

Also, does iJoomla Magazine have it's own home page? My home page is still the default Joomla home page after installing iJoomla Magazine. Is it supposed to look different?
