Valve cover gasket replacement parts?

[vwgtiturbo]

Well, after I get around to researching the proper method of cleaning my engine, I plan to replace my valve cover gaskets (one is visible leaking). Are there any other parts that either a) require replacement as part of the maintenance, or b) are recommended to be replaced since I'll already be there?

As always, thanks in advance!

How many miles are on it?

Just turned 165k this morning, after life changes recently increased my monthly mileage to about 3k/month :-( There are a host of things I'm chasing down now, but I won't talk any trash about her; she's been good to me for 13+ years (well, and she STILL runs, just not optimally hahaha).
