I am new to this message board, but my advice would be to bring your file! Hopefully you've kept a nice folder or log of all your diagnoses, procedures, medications ... etc. It might save the rheumatologist (and you) from any duplication of effort. It sound like you've been through a lot, and it will only make you feel bad if he starts from scratch with treatments you've already found to be ineffective.
I saw my rheumatologist for the first time in August, and again in October. I don't know if other people would agree, but I've found him to be MUCH more understanding than my primary care physician. He looked at my file, ordered some additional bloodwork, and began my treatmment in a matter of 2 appointments, where my primary care physician had no idea what to do after a year of visits.
Also, be honest with the rheumatologist. I really do think they want to help you manage the disease, and minimize your pain. I can say now after about 8 weeks that I am starting to feel less pain in my hips and shoulders, and I'm less tired than I was before. I had been having such sharp pain that I couldn't move my left arm at all, sometimes for days!
Don't be afraid to tell your doctor symptoms that you think are unrelated. I'm surprised to find out how many things ARE related. My finger nails turn blue all the time - I've had that symptom for YEARS, but it didn't hurt so I didn't worry about it. Turns out it's related. I get dry eyes, which I always assumed was from the heat (I blast the space heater at my desk because I can't stay warm). Turns out that's related too. I have something called Sjogren's disease, which is another autoimmune disease that is often coupled with SLE.
So bring all your paperwork and tell the doctor everything. It's a new doctor, you have a clean slate. Tell your story so you can get some relief!
