Advice re using miles for UC returns next year.

Hi,
I'm sure someone will be able to help;
I've been saving up the miles for about 6 years. Haven't spent any for a while, (2 years I think). I've managed to clock up 152k and the girlfriend has about 115k. All disposable income goes into holidays and via the VAA AMEX card!
The plan is to cash them in on the honeymoon next year (2010) December time.
Obviously this is over 12 months away but she's planning the wedding now so I'm starting to think about the honeymoon! We want to fly to Boston drive down to Miami and fly back, taking about 6 weeks in total. Snow to start, sun to finish.
Generally speaking is it going to be better to buy an economy fare and upgrade or just go for the reward seat? I have a feeling that there is more availability for those upgrading as opposed to those pure reward sale fare seats. We need to go on Monday 13th December but the return date is flexible. From a historical point of view is that date particularly busy? What's the earliest we can book (12 months in advance?). If it makes a difference we can go straight to New York and skip the New England leg. We've both done Boston before and, although we love it, we dont really need to go again. I understand there are shedloads of flights NYC bound everyday.
Look forward to everyones opinions.
Thanks,
Craig.
