Editing with RED footage in FCP and everything else

Hello, I have a few questions about working with RED footage on the Final Cut 6 (Final Cut Studio). I'm new to working with RED footage. I'm editing a film that was shot in the RED so I just need a step by step instructions on workflow.

First off, here's my specs: MAC Pro 2.66 GHz Quad-core Intel Xeon with 6GB of RAM. I have a NIVIDIA Geforce GT 120 card and I'm working with G-Tech G-speed ES 6TB Raid (ESATA) drives, 0 Config.

1. Just wondering if I have the best computer to work with RED footage.

2. Do I need a video card like Kona LH or Blackmagic to work with this footage or do I just need it for viewing on an output monitor. Also, will a video card help the speed and performance of the computer when editing and most important rendering the footage when it's done. I heard if you don't have the right stuff for your computer, when you export it would take days. Just wondering if that's true. Also is 6GB of RAM good enough?

3. Right now I'm editing on the proxie files by just dragging and dropping them into FCP. This seems to work for now, but just wondering if I should be working with the other higher files or does it matter? Also, should I be importing the OT files that way or should I use the Log and Transfer window to get those files in?

4. I have no idea have to export my final product to full quality. From what I've been told I export the files to an EDL and it will contact to the Hi-res Master file of the RED. Just wondering how do you do that on FCP and do I have the right specs to do it? Do I need any plug-ins?

5. I have downloaded a few plug-ins from the RED site. Whitepaper, RED ALERT, and RED FCP REDCODE. Do I need to go into RED ALERT with the files before I edit to FCP? I also can't see the REDONE codex in FCP in the Log and Transfer preferences. Do you have to add it or something?

6. Working with the proxie file in FCP, I can't put any kind of effects on the clips like dissolves or fades or even keyframes. It just comes up gray. Does it just do that in the proxie mode and will it show up when I export it to the higher file or is there a setting somewhere I have to adjust.

Sorry for so many questions and I appreciate any help you can give.
