Shannon, definatly go with a cruise control for the trip. It will make things easier and more comfortable. Only use the cruise control when you need alittle break. I have the Throttlemeister cruise control on my R1. It's the same exact setup for the FJR. I love it. In addition to having cruise, the cruise acts as heavy bar end weights. I picked them up at Cycle Gear for well under $200. Go check out

You can go with either the heavy or standard. The standard is pretty heavy as it is, but i've heard from people that the heavy's are easier to use since they are alittle longer. Call me with any questions about them or you can just check it out on my bike tommorow at bike night.
When you are ready, call Catherine at Cycle Gear. She can get them for you. It took about 3 or 4 days for them to come in.
