For instance the white queen, I'm guessing he took the rook on h8 but then why go to g7?
My first advice - count the pieces of both sides that are left, account for the possible pawn captures (as here it is obvious that d2xe3 and b7xc6 and e7xd6 were such). You now should have pretty good idea what pieces were captured on that squares (though how they came there is sometimes harder to guess).
What usually helps me tremendously - find the minimum number of moves for White to reach the position (ignore Black). Do the same with Black. Assume shortest paths for all pieces. Most probably one of the sides will have the exact number of moves required in the PG. So if it is White, Black would have to ensure that White can make all that moves in this shortest time (Black plays to assist White, in other word). Look for "spare" moves - moves that don't obstruct the path a piece should go through. These together with some additional info will quickly nail down the order of the moves (the spare moves are usually the first few before Black can unblock some of the paths).
