Does sound like the master cylinder seals are leaking, but that can be replaced fairly easily. You can pick up a master cylinder for around $70 from a worldpac vendor, it goes for about $250 at the audi dealership, and have a local shop familiar with audis do the work. It's about a 2  hour job to replace the master cylinder. If the master cylinder is gone it's probably a good idea to replace the slave cylinder, but the slave cylinder can be a bigger job. They cost about the same but their location is a pain to work on. Generally if a slave cylinder goes you can't get in or out of whatever gear you're in, while with a master cylinder if it's pumped up you can shift gears. 
If the car has 130k miles it's a toss up as to whether or not to do the clutch. Depending on how abusive you are with the clutch it might just be ready to go or it could have another 100k miles left on it. On my own manual tranny cars I've regularly gone over 200k miles before replacing the clutch and in one case it was the throw out bearing that went and not the clutch. On the other hand my niece went through clutches every 50k miles.

HTH and good luck
