The fur issue, unless you can brush them out(with either a rake, or a brush), I'd advise you to contact a professional groomer. I do have a rake video up on youtube, on the proper way to use a rake. Normally I can get most "clumpies" out with this particular rake, and using the method on the video, most cats don't object(believe it or not!)
The urinating could be a infection(bladder or urinary tract or kidney) and that would be for a vet to check.
Here's the video. http://www.youtube.com/watch?v=vbbC4R9A-f0

Hope this might help!
