Just a quick thought, you're going to have solar radiation come at you… you're going to have to watch out for the Van Allen belt; that brings onto the question of protection against space debris.
A few things to get the thought train going.

Any ideas on what kind of shielding are required? I've been a fan of using layed mylar for insulation, maybe the reflective properties of that would also help to shield such radiation.

I have seen somewhere that high hydrogen content materials are good at dispersing radiation – this is aside from the usual high density metals such as gold and lead… gold of which is expensive and lead of which is quite dense. Of course, with space you either do it right, or not at all.

Also, thinking of high reflectivity materials is good, but highly ionising particles are going to ignore a shiny surface and go straight through.

There's a company that has some shiny new nanotech radiation sheilding fabric. It might be useful, being lighter than traditional sheilding. I'm not sure how good it would be at stoping the kinds of radiation we'd be dealing with, but it might be worth looking at. Here's a link.
