The first time I played through Baldur's Gate 2, I didn't have to learn much. Much of it is automated anyway and happens in the background (like saves, most of level-up etc.). Some info is nice to have, but not really essential. Maybe check out some basics, like what the character attributes do, but other than that you just need to read spell descriptions from time to time.
Personally I was more frustrated with DA:O, since the tooltips contain no specific information whatsoever and even if using the "Extended Tooltips"-fix, there is still a lot of info that one has to gather from the internet. (similar to Dark Souls >> all these stats, but no description, no manual, no nothing).
