Oh, yeah, there's plenty. Back issues of Spider-Girl are still being put out in digests (10 and counting), all of Amazing Spider-Girl is now out, and thankfully it's still being produced slowly online and in Spider-Man Family, and all of JMS' run is in trades, going up to around .. 10? 11? of them? Not sure because I'm a little behind and the numbering gets thrown off by The Other (all Spidey titles crossover) and then Civil War/Back in Black, which led into One More Day. Or you could wait for more Ultimate JMS trades to come out. Don't get them mixed up with Ultimate Spider-Man, which is an entirely different universe (with an awesome May and pretty good MJ).
Going back farther into the past, there's good MJ and Felicia, but I have no idea what's in print and what's not, sorry. Try and track down Roger Stern's run -- despite my deep, deep ARGH over what he's doing now, it's good stuff.
