The aim of the opening is to reach a playable middlegame. This means developing your pieces to where they do the most good. Instead of thinking of what SQUARES youre pieces are on (or SHOULD be on), it is better to think about which lines or diagonals are controlled by your pieces...and which lines can be taken over or challenged by your pieces in case they are being controlled by your opponent. For instance if the a1-h8 diagonal is of importance, then that is the key issue....whether there is a bishop on b2 or c3 controlling it it of secondary importance, unless there is a specific tactical situation to be attentive to. Sometimes it is helpful to think of a piece as an octopus with tentacles reaching out toward your opponent's position. Obviously, if (for example) you have a bishop which is blocked by your own pawns, then the octopus's tentacles are rather short, and not too scary. Try to give your pieces their maximum scope, and train them toward the weak parts of your opponent's position.

You are talking about when one side castles kingside and the other castles queenside. There are several dynamics that are inherent in such positions, coovering them all in detail would be difficult, but here are some ideas to look for: 1) Pawn storms are the order of the day. Typically if white castles queenside and Black castles Kingside, then white will fling his kingside pawns forward, while black will do the same on the queenside. 2) There is the "extra tempo" to consider for the side that castled queenside. What I am talking about is the extra tempo involved in making the move Kb1 or ...Kb8 to protect the "a" pawn on the queenside. This can make a big difference in attack and defense. 3) Another dynamic is whether the "d" file is open, whereupon the person castling qieenside gets a rook immediately on the open file. Sometimes this can speed up an attack.

Judit Polgar is well-known for her ability to conduct attacks in such positions. A good study of her games will repay the effort twice over.

I wouldnt worry about playing fast.......if you are losing on time, then play at the next slowest time control until you are comfortable. It is a bit like a musician learning his scales. The fastest players practiced very slowly at first. When they become second nature, only THEN does he speed up the tempo. Playing bad moves fast will not help you improve....learn the basics first.
