Queen's Gambit

The main line goes as follows 

Any suggestion? 
So far this is what I (the computer) came up with (with quite a bit of sidelines)so far

Castleing first runs into 

I know the ideas fairly well (minority attack and advance in the center and sometimes Ne5 followed by f4)
The problem with the h6 line is that it's hard to prevent the exchange of dark-squared bishops and if the bishops are exchanged e3 becomes too weak after f3 leaving White with only the minority attack which also isn't as effective as in the line where the knight is on f3 because the knight is more active there. Also it blocks the retreat square of the bishop if Black ever plays c5-c4, forcing it to go to f5 where it will likely be traded as well.

So the only other option is 0-0-0 with a kingside attack but those lines don't promise much either (along with the fact that it's not so much in tune with my style of play.).

The problem isn't so much that Black trades pieces, it's that by doing so it prevents one very important plan for white after which whitee doesn't have much of a chance for an advantage.
Now I'm considering a move order like 

In the main line White doesn't push until everything is prepared ron e1 or d1 h3 a3 and b4 to prevent c5 sometimes and Kh1 I don't think it'll work with Ne2 though since the inclusion of h3 weakens the dark squares quite a bit.
