TKO 600 Parts List

Tranny is on it's way here so I'm wanting to make sure I have everything to install it correctly.

Parts list:
-Tremec TKO 600 Trans
-Tremec Aluminum Bellhousing
-Promotion 26spline Clutch
-Steeda Tri-ax handle & Shift Knob(lol)
-MM Quadrant & Firewall Adjuster
-3 Quarts of Syncromesh

That's what I have so far. Here is my questions about the parts I'm missing:
1. Will the stock clutch fork work?
2. I need a 31 spline yoke for my DS, can I buy the 31 spline Aluminum DS that Ford Racing sells? If not, can I just buy this yoke: (Click Here )
3. I have the factory crossmember that came with my T5, what's the deal on using it with this tremec? I've read that you have to "grind tabs off so it'll slide" or something. Anyone got any pics or a better explanation?
4. Should I buy a poly trans mount or use the one from my T5?
5. Where can I buy a 26 spline clutch alignment tool?
6. Do I have to check the bellhousing for alignment?

Thanks!

Thanks, I'm buying the clutch used and he said he doesn't have one. I'll find one somewhere.
