Lower fermenting temps, especially for whites can retain more aromatics ( and other things) from what I understand and fermenting at higher temps can cause these to be lost. However, I also understand that this does not apply to kits wines; in order to not lose these aromatics, etc. the grapes/juice must be kept cool throughout the process from picking to fermentation. Since kit wine juice is heated during pasteurization, this "keep cool" process is interrupted and no benefit from lower fermenting temps is realized.
Regarding stuck fermentations, I have no experience with one yet but I believe the lower the SG when you get stuck, the more difficult it will be to restart - presumably because the sugar content is lower and alcohol content is higher. I don't know if there is a cutoff point ( say 1.010 - 1.005) but others may have better info on this.
One suggestion for increasing your fermenting temp a little is to wrap the bucket/carboy with something ( I use an insulated shirt) - the must will generate its own heat when fermentation gets going and this helps to retain it.
Good luck .. Doug
