Welcome to the forum! I would suggest the 100mm non-IS and the ringlite. It will provide more flexibility than the 100mm IS.

It really depends on whether or not you have a ringlite. A ringlite is much more efficient than a speedlite because you don't have to worry about positioning it. (At least, it is better for photographing insects. It would probably not make a difference for photographing flowers on a tripod.)

They are very different... I wouldn't worry about it; if you find that you don't use the 85mm anymore, you could always sell it.
