How do you calculate the lightmaps for your levels? Is it radiosity based? Know any good websites where i can learn this stuff?

No, but a few good books.
Please have a look at this FAQ: http://www.ca3d-engine.de/phpBB2/viewtopic.php?t=32
I just added two books there about radiosity. "Computer Graphics, Principles and Practise" has a good section about radiosity, and the two books below it are all about radiosity. The one by Ashdown is no longer in print, afaik.
I used all three for implementing CaLight, but mostly the upper two.

Just as a point of curiosity, what are you impressions of photon mapping?

To be honest, I don't know enough about it yet and cannot clearly relate or compare it to ray-casting or radiosity methods, but I'll soon have a thorough look into http://graphics.ucsd.edu/~henrik/papers/book/
When I'm through with the book
, maybe it will eventually find its way into Ca3DE. Maybe this becomes a booster for CaLight, after all.
