Well, re 300D vs a 40D?, no brainer, woefull USB1 on the 300D, really frustrating. Live focus on the 40D (and USB2) is a killer. Weight problem?, really?, dont think so, and $300 vs $1200?, well worth it IMO.
Having said that, the megapixel diff is mute for astro, if money is a prob, the 300D would do at a pinch.
