No, BG1 and BG2 are discreet games. Having BG2 installed will not affect BG1 in any way.
However, installing the BG1 expansion Tales of the Sword Coast will enhance BG1: it does not change the ending, but rather raises the XP cap, adds more spells, new items, and four new areas to the game. ToB is similar in that it adds new spells, weapons, armor, etc., to BG2. But as I understand it, you don't play the ToB modules until you have completed Shadows of Amn. Or? Not too long ago I had BG2/ToB installed and there was a distinct option on the start up screen for ToB, so that was my assumption. But please someone correct me if this is wrong.
