It's difficult to really include everything possible since sometimes it's really hard to get across personality in Wiki articles. More than just that, the art tells a story too so you really need the combination of both. Actually, that site I linked you to (uncannyxmen.net) contains the most comprehensive biographies I've seen for the X-Men characters so if there's anyone else you want to check out I'd suggest doing so there. It's more accurate than Wikipedia and Comicvine since it provides textual citations and scans of panels. They also have costume lists and notable appearances lists.
Rogue's actually led her own team before that. She was voted in as leader in the early-2000s. But it's true... your memory sucks. You really don't seem to remember much and require a lot of memory jogs. Haha! Sucks, doesn't it?
It also doesn't help that the '90s issues weren't collected in entirety in TPBs. However, there are some stand-alone issues that you could theoretically pick up and understand quite well. There's a good two issue arc in the adjectiveless X-Men title that is pretty cool. As I said above, I recommend checking out uncannyxmen.net for more information on the X-Men. You can check the "issue checklist" section of her biography for some of the notable appearances Storm has made.
