I've done nearly exactly this, except that the spider on my Quarq was a Riken provided as a warranty replacement on my original S975 crank, and I was going from BB30 to GXP. I bought the Force 22 GXP to let me get rid of the shitty BSA30 adaptors I was having to use in my old P3C, and to shorten the crank arms.
Things worth knowing;
1) The original threadlocker will be as stong as Arnie. You can weaken it by heating it up - a soldering iron placed into the top of the bolts does the trick.
2) Torque wrench needed for refitting, the bolts need to be torqued up progressively. Also the bolts are Torx heads (can't remember the size off top of my head).
3) You will need a long bit extender for your torque wrench. Because the x3 bolts are so close to the crank spindle your torque wrench head will almost certainly foul against it. You need a long enough extender to bring your wrench head out above the axle, if that makes any sense.
I actually have the official Quarq/SRM illustrated procedure that they provide to their dealers somewhere on my computer. If you PM me your email I can ping it over (assuming I can find it!).

Rich.
