As for the Java unresponsive thing, that should not be a big problem. When I play a modpack like FTB, the screen gets tinted white (a sign on Win 7 that it's unresponsive) while it loads all the mods. It usually just means that Minecraft is busy with something (but sometimes Minecraft gets very unresponsive right before it crashes).
