Captain America, Nova, Incredible Hercules, and Immortal Iron Fist are the best of the best that Marvel offers.
Nova and Incredible Hercules are both having Secret Invasion tie-ins, but they sound like a lot of fun and they're far removed from the stuff that the main event is about, and I doubt you'll have to worry about any controversy over someone randomly being revealed as a Skrull. The Skrulls attacking Earth decide that Nova, having recently gained the power of the entire Nova Force, is too much of a risk, so they send agents out to kill him. In Incredible Herc, Hercules gathers up a bunch of Earth's gods and leads them into battle against the Skrulls' gods and the enslaved gods of the races the Skrulls have conquered.
