Trashing Pro Tools, Switching To Logic 6, need hardware advice Options

[a0k1a]

So this is what I have:

Powermac G4 Dual 867
1.5 Gig RAM
Digi 001
Pro Tools LE 6.0.1 with 1.1 CoreAudio Driver
Reason 2.0.1 (whatever) (waiting on 2.5!!!)
Oxy8

This is what I do:

Make beats using Reason. 1 painstaking track at a time.
Export loop as audio
Import audio to track in Pro Tools
Record vocals (just for listening purposes, lining up syllables to beats, whatever)
I use maybe 30 tracks total for a song (fillers, sound effects, background vocals, etc)
Take the tracks to a real studio and record my vocals for real
Mix down, press to CD
For use later on

So with that said...

Pro Tools LE 6.0.whatever is a great product in and of itself...minus the ceiling on MIDI stuff as most of you know. I've found that there are a limited of options as to RTAS plug-ins. And they're freaking expensive!!!

So, I'm back at the beginning.

I'm going with Logic 6. Probably platinum even though it is a bit much for my purposes at the moment eventually I will need every bit of it ( call it high hopes ).

So my question is this: What hardware should I use? Should I stick with my Digi 001 interface? Will Logic 6 vibe well with it? Any experienced users there?
I'm thinking about selling it all and going with an EMI 6/2m. But my concern there is a microphone. Any suggestions in regards to the mic issue if I do go with the EMI 6/2m? Should I be concerned about latency because it is a USB interface?

Thanks for ANY advice in regards to these and any relevant questions!

Okay, I guess I didn't do as much research as I thought I had done. It seems that Emagic discontinued their Audiowerk cards. Anyway, I would still have to get a mic preamp if I went that route. So, I'm going to go with the EMI 6/2m, a mic pre-amp, Logic 6 Plat. I had issues with latency with the USB thing, but since I won't be recording more than at the most 2 tracks at a time there should be no issues. Don't you hate it when someone asks you a question and answers it himself? Thanks for your advice Synth....it seems I won't be banishing my Digi 001 altogether. I may have some use for it after all!
