Will I run into any trouble importing and reading/editing this footage?
I won't need to export to the same format. .mov will be just fine when all is edited.
Thanks for your help.
You should not have any problem importing and editing ProRes 422.
When the time comes for export, you might consider Avid DNxHD.
Avid Codecs 2.3.7 - DNxHD (pc or mac) / 'virtually lossless'

What is Avid DNxHD?
You mean I can't just export to a .mov format?
Sorry if I am not that experienced.
Avid DNxHD is a free, high quality quicktime (CS6) codec.
You can download and install from the link above.
Once installed, you can encode .mov files using this superior codec.
Or, you can just use the ubiquitous H.264 codec for .mov encoding.
