Answer 1

I'm running the same model Duo with a 120GB drive and an external LaCie. It does not support the 800 Firewire, just the 400.
Aperture runs adequately fast, although after two months I'm still learning a lot about the features. The search HUD seems a bit slow, but I do have alot of pictures.
My Aperture Library is 14GB, 13,000 files, 90% are jpegs. All picture files are referenced and take up an additional 17GB.
I found Aperture (and Parallels) choking whenever the free space on my internal drive gets down below 6-8GB. Some non-Apple forums recommend keeping at least 10GB free for working with media intensive apps like Aperture. I also find that even when I quit Aperture, it doesn't free up the temp space on the disk drive it had used. Restarting regularly recovers the 1.5GB or so that Aperture was leaving behind after quitting.
I'm slowing breaking the big project I had with 11,000 files into several smaller projects and migrating the referenced files to an external LaCie. File management, renaming files, finding duplicates, etc., is not an Aperture strong point, (Expression Media is better at file and metadata management, but has limited editing and integration features with iLife, etc.) but over all I'm satisfied with performance on the Core Duo with an external monitor attached.
