To get a sense of what's going on in Gaza right now, just go read Laura Rozen. She's got all the essential links and analysis. One thing, though, that I haven't seen mentioned yet among all the talk of possible local brushfires (Gaza, West Bank, Lebanon, Syria, etc.) is the impact Hamas-Israel and Hezbollah-Israel conflicts might have on Iran's activity in Iraq. The Iranians have already demonstrated how much they can contribute to improving the security situation there. A three-front war between Israel, Hamas, Fatah and Hezbollah would seem like the kind of scenario they would use to demonstrate how much they can contribute to worsening it.
