If you wanted to dip your toe - the Canon 50mm f1.8 is probably the best bet to start with. It's cheap $149 rrp , a bit plasticy!!! Build quality is not the best but results are sharp. I have been looking to get a decent budget Canon prime, and the voices in my head are telling me to get the 85mm f1.8 which is around
$500 on ebay.

I've pretty much settled on the 40D with the 17-85 lens, as you say a good walking around camera
After reading a few other threads here, I was also considering the 85m f1.8 ($499)
I'm not sure whether a more powerful lens such as the 135mm f2 ($1599) is of any advantage for astro work.
I can see the advantage of the fast speed but does the increase magnification make a big difference?
