"Re bugs, I don't think the tent will help much against ticks, since you typically get ticks on you by brushing against bushes on the trail. "
On the contrary, in the OP's region there are areas where ticks descend upon you in horrifying numbers, especially mid-summer to fall. This I find especially true on trails shared with equestrians. I have been covered in ticks more than twice and will never sleep in this region without a noseeum shield. Some of the ticks are so teeny they look like little freckles and you don't know they are on you until you get home. I have many scars from tick bites. I use a Ti-Goat bivy but I may switch to some kind of bug shelter under my tarp this fall.
Best solution in this area is a good tarp and a bug net with floor hanging under it. It's generally too hot aroung this region for a full tent, IMO.
