I have a Mandevilla that is two years old.I put it outside in the summer. I brought it in last year and was able to keep it in qa very sunny window. It did very well. In summer I took it out again, and it did great. Now I have it inside again but do not have as much sun exposure as last year. It has dropped most of its leaves, but is growing from the ends of the vines. My question is: can I cut this back severely to allow it to grow all new shoots, or will this be detrimental?

Yes, you can cut back the stems pretty drastically, and new growth will begin quickly. You should keep the mandevilla in a sunny spot but make sure that it isn't getting hit by heat coming from the heat vents.
