I just received my first computer analysis today. It was very helpful, however I'd just like to confirm what the score it gives means?

score = points ahead. White to move. Lets say it say 0.68 that means you are 68/100 of a pawn ahead. THis however is an estimation and can change fast.

fair dos. So when it says +0.68 is that me or is that white or is that the person making the move?

Bump.

I believe + is good for white and - is good for black

yes, that is right.

Hey is there any software(preferably a free one, but paid is okay) which i can use to analyze my games with scores using .PGN files?

arena chess gui (just google for it).

then download either stockfish or houdini chess engine and you are set.
