Rog,
Looks like you've got a few nice lenses there. I wouldn't worry too much about the IS lenses. They work well under some conditions and not so well under others. Two stops, maybe three at best, but like anything else, operation is a compromise between the bandwidth and settling times of the image stabilizer servo loops. For your skiing action shots, they aren't really necessary.
Now one thing you'll have to remember if you go decide to go with a Canon D30 is that because of it's imaging array size, all of your lens's focal lengths will multiply up by 1.6. While this makes your 300/2.8 into an equivalent 480/2.8 which in some cases is good, it will also limit your wide angle capability on the other end. That nice wide 17-35 now becomes a 27-56, so just beware of the compromises. I have a 17-35/2.8 AFS that was made to replace the older 20-35 because of the 1.5X multiplier of the D1. I got so sick of the 20-35 not being wide enough on the D1, compared to what I was used to with the F5, that I went out and got the 17-35. When this wasn't quite there, I had to get the 14mm/2.8 rectilinear also just to get back near the original 20mm end for the digital equivalent of 35mm.
I have a real lens quiver problem myself, only there all Nikons rather than Canons:
14/2.8 AF-D
16/2.8 FE AF-D
17-35/2.8 AFS
28-200/4-5.6 AF-D
28-70/2.8 AFS
50/1.2 AIS
50/1.4 AF-D
85/1.4 AF-D
105/2.8 Micro AF-D
80-200/2.8 AFS
300/2.8 AFS
400/2.8 AFS
600/4 AFS
1.4X TC-14E
2X TC-20E
My scanners are a Minolta Dimage Scan Multi with SCSI and a new Nikon Coolscan 8000 ED with 1394 Firewire. Both of these will handle APS, 35mm, medium format from 6X4.5 through 6X9 as well as 16mm xray transparencies. For regular scanning, I just use an Epson 1640. They make this with a transparency adapter for slides and call it the 1640 photo for maybe $350 or something. It isn't as good as the dedicated scanners above, but it does pretty well. The Minolta is a few years old so it doesn't have any "fixerup" programs in it, but the Nikon has Digital Ice and Digital Gem.
Printers are all Epson: 870, 1270, 2000, 5500. Color and gamma calibration is handled with Monaco EZ Color using IT8 targets for all scanners and printers (which takes a f**k of a long time to do right!). Monitor calibration is facilitated with a MonacoSENSOR Colorimeter that I suction cup to the screen during the process.
I haven't skied in years, although I still have my Ohlin Mark IV's around here someplace. My son snowboards. We snowmobile when there's snow and sometimes when it's not so frozen, like this year.
Why don't you email me if you need any more information. I'd be happy to help you with your decisions if I can.
