Welcome to AFF
llamar.
Airpasses are generally only available to people from outside the country for which they are being used and must be purchased from outside that country. They can be good value and offer reasonable conditions. Certainly worth looking into.
I like to book hotel stays using the hotel's own on-line booking systems. I always book a rate that can be cancelled without charge, preferably on the day of arrival. That gives me maximum flexibility if I change my plans or find a better rate even at the same hotel (yes, that happens). I try to avoid pre-paid stays even if they are a little cheaper. Some places you can't avoid pre-payment, such as staying within the Grand Canyon National Park.
I look for the major hotel chains and use their web sites. For personal vacation stays I look for places like Best Western, Comfort Inn, Hampton Inn, Travelodge, Sleep Inn and even Super 8 can be ok. I do also look for special deals at more up-market places as they can be good value, especially on weekends - places like Hilton Garden Inn, Doubletree, Holiday Inn etc.
Places like
Priceline can offer great savings on accommodation. For information on using sites like Priceline, have a look at
Bidding for Travel. I don't personally use Priceline, but many people do and have been very satisfied with the huge savings available.
I have used
Travelocity a few times when they offer better rates for some things, especially car rental. I found their rate for a one-way rental (had to be between airport locations) was significantly cheaper than for the same car type, dates and locations directly with the same rental car company.
I generally don't use tours so can't comment too much there. Perhaps see if you can book directly with the tour company. The travel agent will earn a commission from booking you on a tour. They don't get much commission on airfares these days. So if you want help from a TA, it might be best to use a tour booking as a carrot.
One of the best places to get first hand information from experience travelers and locals on the places to go and the places to avoid, is the
Travel & Dining: Destination >> United States forums on FlyerTalk. I used these extensively when planning a 3 month round the world family vacation. Its amazing how helpful it can be getting answers to specific questions from people who live around the corner from the place you are asking about. AFF is good for Australian information and experiences of Aussies traveling to other regions, but FT is great for USA and Europe local knowledge.
Make sure you have appropriate travel insurance. Many travel insurance policies do not cater for FF award tickets and the strict conditions that can be imposed by the airlines on the use of those tickets. Ask the question of the travel insurance provider before paying for the policy. A good place to learn about travel insurance policies and compare products is

Make sure you do your research. I found the planning part almost as much pleasure as the trip itself (we were traveling economy - the trip would have won out if traveling in business or first class

).
