Todd the Vinyl (and Headphone) Junkie sell the Grado "flat" pads, which most people prefer to the stock "bowl" pads that come from Grado. His online store is accessible from www.head-fi.org (Todd is one of the head-fi sponsors, so you will find a link to his store on the home page). I think they cost about $15 per pair (or so) but I'm not sure.
There are several DIY guys at head-fi who could replace the cables for you. Depending on which Grados you have, it may be worth it to consider one of the higher end replacement cables such as those offered by head-fi member Xanadu777 (Larry). His website is www.headphile.com. He uses silver wiring which provides significant sonic improvements. The cost is about $100, more or less, so it would make sense with the RS-1, RS-2, but not the SR-60, SR-80, etc.
There are a bunch of other guys over at head-fi who could help you if you're looking for a quick fix. Last but not least, John Grado is notorious for providing first class customer service. Check Grado's website (they're based in Brooklyn); I'm sure they can help.
