$2000 for a stay should net 10k Grazie points, which would get you halfway to Gold. If you aren't already doing it, make sure you also bill any meals in the hotel to your suite.
I don't have any experience booking via an ICH account, so I don't know if they let you double dip.
The primary thing that gold status gets you is that it makes it easier to get to gold status with room charges the next year. Oh, and a free airport shuttle. Other than that, pretty useless IME.
