A) That may sound harsh, but at the moment your tactical skills are so low (1188 according to your profile) that I don't think teaching you advanced positional plans is going to bring you much success. You missed two simple 1-move tactics in the game you posted (27.Ra6? and 28. Nxe6??).
After 28.cxd4 Qxf4 29. Qxf4 Rxf4 30.c3 at least you would have had good chances of holding the endgame thanks to your active rook and the drawing tendencies of rook endgames.
Of course, we could talk all day long about positional play against weak pawns, but it is useless if you play a sophisticated positional 10 move plan against a weak pawn only to blunder a piece/walk into a mate shortly thereafter. I don't know if you use the chess.com tactics trainer, but I highly suggest getting your tactics rating up to around ~1600 and only then focus on advanced positional play.
B) Just to show you that tactics are always a part even of seemingly quiet positions, let's look at Jkaen's suggestion:
His general plan of blockading/attacking Black's a-pawn looks good as far as I can tell, however 23. Ra6 allows 23...Qb7 and if now 24. Rxe6 Qb1 is mate. That means your positional goals always must be supported by concrete tactical lines.
So an alternative would be something like:
23.g4 Nh6
24.Ra6 Qf7 (now Qb7 doesn't work because there is no back rank mate threat anymore)
25.Qg3 (supporting the knight) g5
26.Nh5 Qb7
27.Ra1 Ra8
28.Qe3 Nf7 (defending g5)
29. Qc1 and White has managed to move his Queen over to the queenside in order to help stop the potentially dangerous a-pawn.
I am not saying this is the perfect plan, but at least it's a possible way of playing with a certain goal in mind and obviously Black's passed a-pawn must be taken into account.
