As it's my first play through, would you say it's worth redoing about 10 hours of content to get them?
Thinking now maybe I just leave it and use it as an excuse for a second playthrough?!
It's completely possible to finish Act 3 without recruiting Jaheira and Minsc. You'll gain more EXP and allies with them, as they have substories, but they're optional. They are not mandatory for the progression of the main plot. Unless you're a fan of BG2 and ABSOLUTELY MUST collect every single character, you can leave them for a second playthrough.
I don't think it's possible to see EVERYTHING in 1 playthrough. If you're doing a Tav run on your first playthrough, I would ABSOLUTELY recommend doing a Dark Urge second playthrough. The Durge playthrough gives you personal quests that tie into the main story. Honour Mode is also a lot of fun. The fact that you cannot control everything adds pure chaos into the mix. You'll find yourself fighting battles and facing legendary actions that you never ran into previously.
