In general, if you are asked to meet someone somewhere, it should be marked on your map. It wasn't really intended to provide hints, or necessarily include everything mentioned during dialogs, etc.
In character creation (or once you reach level 3 and get a talent point) you can have one or both characters take the Lone Wolf talent, for an 80% vitality boost, AP boosts and an extra ability point when levelling). The downside is you can not recruit a companion for each main character that takes this talent), but if you don't want a larger party, anyway, that isn't a problem.
The Raistlin talent goes good with Lone Wold, as well (doubles AP recovery, but halves your base HP); you get more AP to use in combat, and your health still gets a net bonus.
