A Typical Game in the Queen's Gambit

Typical for me, at least. :\  As white, I enjoy playing the Queen's Gambit (or d4+c4 in response to the Indian defenses, since I suppose those aren't technically called the Queen's Gambit anymore). However, I find that I have a hard time formulating a middlegame plan once the first few moves of the opening are made. While I'm sure my endgame technique needs a lot of work, I feel the weakest in the middlegame. I know the book moves of the openings well enough, but often feel at a loss once I get past that stage. This game is an illustration of this deficiency in my play. Though I manage to win in the end, I really feel like I could have done better after the opening stage.

Please feel free to leave any comments or suggestions for improvement.
