At the footer of this it also says synchronizing with network and has been like this all day (slowly moving) Am I correct in thinking that once this sync is complete my total will show as 3.00 and then is this the bitcoins are stored on my desktop?
Yup. It will show up in your wallet once the synchronization is finished. As for the sync speed, it depends on how fast your connection is and how many peers are you connected to. The bitcoin core wallet's blockchain data is sized in GB, so don't expect a speed download of data if you have a slow connection. You might have just tried a small wallet like MultiBit or something if you don't want to have a copy of the whole blockchain.
