This is how I reply. I try to end with a "call to action". (I'm open for constructive criticism on this):
Thanks for your inquiry and congratulations on your upcoming wedding! We are currently finalizing our calendar for 2013 and I'm happy to say that we still have your date available.
Our wedding packages start at $xxxx and most couples spend $xxxx - $xxxx on their complete collections. Attached is our current price list for your reference.
When you are ready to schedule a consultation to discuss the details of you wedding, call us at (xxx) xxx-xxxx or send us an email at email@example.com.
As far as negotiating goes: everyone is different. Some negotiate all the time, some never do. Personally, my prices are my prices and are what I need to charge to run my business. If they are on a budget, I will work with them as far as taking items off their package in order to lower the total cost. So if they say "We have a budget of $xxxx and we want A, B, C and D" and that is less than my price for those items, I will say "I can meet your budget and provide the most important items on your list (A, B, and C)." If they really need A, B, C and D and that is their absolute budget limit, I can provide references for some other local photographers that are in their budget.
