First off, if you're new to RED, you should read the following whitepaper:

If you want to know more how the Kona 3 would help with the RED workflow, check out his whitepaper:

If you're going to try to edit with the RED proxy files, then you'll most likely need to change you're RT quality settings to medium or low. I suggest using a program like REDRushes or ClipFinder to export offline files to edit with, as I don't completely trust editing with the proxy files. This will allow you to edit with files that are much more edit friendly and at the full quality of the codec you choose instead of editing at low quality with the proxy files.
Also, the Kona 3 doesn't add the functionality of being able to playback a RED proxy files at high quality. That has more to do with your machine than anything else.
