Default Doing the coupler next week... questions

I'm finally going to replace my coupler next week. I'm gonna try to order the parts tomarrow. I went through the shopping list, so i'm going to go to my dealer to get the gaskets and such if auto-zone doesn't have them. Is there any reason why i would need the gasket to the thermostat? Also i found a lot of good pictures, and helpful stuff, but does anybody have a full writeup of how to do it. This is an M62 by the way.

Ya'll tell me if i'm missing a step here.

1. reieve fuel pressure
2. take of fuel rail (i don't really know how to do this one)
3. remove all the vacume hoses ect.
4. unbold and remove supercharger.
5. remove fluid, crack it open (no prying)
6. replace old coupler with new. (seal nosecone), new fluid
7. Replace gaskets and such on the shopping list.
8. put supercharger back on.
9. bolt it all back up.
10. replace fuel rail, vacumehoses, ect

Ok here are a few questions i have.
1. How do i bleed the air out of the fuel lines when i'm done
2. as i mentioned earlier, taking off the fuel rail
3. what kind of sealant for the nosecone?
4. Anything i missed or did wrong?
5. What to clean injectors, and other stuff with.
Thanks in advance. You guys rock!!!

1. reieve fuel pressure
2. take of fuel rail (i don't really know how to do this one) EASY. YOU'LL SEE THE BOLTS.
3. remove all the vacume hoses ect. MARK THEM AND TAKE PHOTOS
4. unbold and remove supercharger. YOU NEED TO REMOVE A STUD FROM THE ALTERNATOR BRACKET. DOUBLE-NUT IT AND REMOVE IT OR THE SC WON'T COME LOOSE.
5. remove fluid, crack it open (no prying)
6. replace old coupler with new. (seal nosecone), new fluid USE THE PROPER SEALANT, AND LET IT DRY FOR AN HOUR BEFORE FILLING----OR FILL AFTER TOTAL REASSEMBLY.
7. Replace gaskets and such on the shopping list.
8. put supercharger back on.
9. bolt it all back up.
10. replace fuel rail, vacumehoses, ect

Ok here are a few questions i have.
1. How do i bleed the air out of the fuel lines when i'm done DON'T WORRY ABOUT IT. IT WILL TAKE CARE OF ITSELF.
2. as i mentioned earlier, taking off the fuel rail 10mm BOLTS...3 IF i RECALL.
3. what kind of sealant for the nosecone? RED GASKET MAKER FROM THE DEALER....DETAILED IN THE STICKY POST IN FORCED INDUCTION.
4. Anything i missed or did wrong?
5. What to clean injectors, and other stuff with. FUEL INJECTOR CLEANER AND INTAKE-SAFE THROTTLE BODY CLEANER.....GET 3 CANS.
Thanks in advance. You guys rock!!!
This is for the M90, but directly transfer to your car:

Wolfe, have you seen my "M62 Rebuild with Pics" post? There are detailed pics of the shopping list and sealant. Or go to my website. You'll see them in the gallery at the bottom of the bonneville links list.

Yeah. I've looked over it many times. I feel pretty confidant about doing it now.

TB bracket is held by a small screw on the TB, and one or two nuts also holding an exhaust heat shield. I don't recall how many there. You also have to disconnect your throttle cables. Mark them so you don't get them mixed up later, and put the clips in a safe place.
