I returned recently also. So some of my knowledge is limit but my two cents.
It depends on what you want to do. If you are looking to level fast, then stay away from the TLP servers. If you are looking for the original-ish EQ content leveling, then there are several TLP servers that should fit your fancy. The only thing that not having the remaining expansions is max level, and access to some task/merc/equipment advancement. But you can still get pretty far up until you want to buy those last three expansions. The problem you will mostly find is ensure you can get buffs for leveling (temp, virtue, DS, etc.) Sometimes its really easy because one person will login like six alts, and buff you. But if everyone is idle it's a pain.
The other thing is in addition to the early level cap of 50% of your level difference, there is a max level cap of 30 levels. so to group with a 115, you have to be 85 to get exp. Also, if you follow the hero's journey series of achievements (and quests) it will level you fairly well, or you can just grind the entire time if you want.
IRT your 1 g 2 non-paid accounts, I am actually about to make a post asking for a good setup for my boxing attempts.
