In terms of books get the Sven Hassel series.
http://en.wikipedia.org/wiki/Sven_Hassel Even the egnlish translations are a fun read with lots of action, dark humour and although some of the plots get a bit far fetched in the later books, they give a pretty good picture of what life was like for the German tank soldier.
One of the got made into a pretty bad movie in the '80's. It was based loosely on Hassels book Wheels of Terror but was names
The Misfit Brigade for some reason.
I also highly recommend
The Good Soldier Švejk WWI again but hilarious. There are a few versions around but I think the 13 part German TV version is best.
