Have a careful look through your apps: are there anty you never use, and cannot foresee using? As an example, I never use garageband so deleted it.
Also, have another look at your photos. Download and run iPhot Diet (find it on Versiontracker): this will gain space and make iPhot run more smoothly and faster. Then make up albums of the ones you really like, the ones you show to friends etc, and then back up the others: I would suggest to CDs and to an external drive.
