GR Install + Holiday Bonus questions

Okay, I just picked up the Going Rogue Complete Collection from Best Buy, and I've got the DVD sitting here and the serial code on the quick reference card. Couple of questions:

1) Do I need to actually put in the DVD and install the program? (I already have CoH/CoV on my PC and am actively playing it.) Or do I just need to upgrade my account with the serial code?

2) I plan on upgrading to the Holiday Bonus 14-month plan. I don't think that the free month included with the GRCC interferes any with the bonus, but to be on the safe side, should I install (or punch in the code for) GRCC before or after I put myself on the 14-month plan?

Nope.

Yeppers.

It shouldn't make any difference. I've added EVERY expansion that came with a free month and I bought the holiday plan on both of my accounts last year. No conflicts yet.
