Thats a big gear ratio. If you are pretty new to FG's I'd drop a few gear inches and that will make everything infinitely easier and more effective, other than moving at 35mph. As for trackstands I don't think of riding into a track stand as more than one thing but I look at anything I do on a bike as one smooth and connected action. So don't think in sepparate steps like, I'm riding, now I need to stop, now I need to trackstand... etc. Think of how to do all of that in one fluid motion seemlessly connected. this is what allows a rider to apear so smooth and comfortable on a bike and shoot holes and lanes that others don't even see. Work on that and visualize it as you ride and as you're not riding, do that along with the suggestions above and more practice and it'll come easy.
