Hi- Well, I am in the same boat. The status of support software as I know it is as follows:
Breeze Browser now has 10D support (as of a post I saw today), Pekka may get a 10D and then get interested in modifying the Linear Sharpen action for the 10D. The Fred Miranda ISOR action- I have modifed for 10D use. I'm sure he will release new 10D actions. The RAW plug-in for Photoshop now does have 10D support.
Qimage is the item for printing. I can come close with a lot of work in Photoshop, but I still cannot match the depth of color and resolution from Qimage.
And I don't even have my 10D yet!
Have fun-
Bob
