advice on first try at replacing guides???

[mag minnow]

Hi,
I'm looking to replace the guides on a St. Croix Ben Doerr SS100M2 that I have. I bought it back in 2002 and like it enough that I want to keep it alive a little longer. (Last w-end I managed to break all the guides). I've been reading some of the posts here and checking out some of the online supplier websites for information. I'd like to replace the guides myself for a couple reasons. Mainly I want to get this back and operational as soon as a I can and the original guides never impressed me.

1) Is there a one stop location where I can order what I need for material on line and...

2) If I were to tell them the rod model, would they be able to tell me the corret guide sizing I need to use? I think the guides are sized correctly. Also, if anyone can suggest a replacement guide that would be a good match for the rod matched with braid I'd appreciate it.

Thanks...
