how much is the f-pawn really worth?

I think the sacrifise won this for me:

I think blacks poor defense won it for you. After you 'sacrificed' your trapped bishop, black was rather silly for opening up the center right away.. The main mistakes black made were 9..exd4? and 12..Bf6?? I would have preferred 9..b4 and 12..Bxd6..all in all though black let you do such a fun attack, but you did a good job in exploiting his mistakes.

The f pawn is worth a point, the knight is worth a bit over three.
That help?

This only works in Bughouse or against the weakest opposition. If you play anyone that knows halfway what they are doing, they will take your Knight, consolidate the position and then start exchanging pieces until you're left a piece down in the ending.

In bughouse, yes! In chess, usually no!

Edit: Sorry, looks like the previous post beat me there
