Startup disk full message

I have a mac book pro around 3 1/2 years old, it has a 73gb hard drive and it seems to be full.
I have just purchased a 320gb hard drive and used time machine to back up to the external drive.

I assume i need to remove files from the laptop but i am not sure if this is the best thing to do.

I am not a mac expert so anyone with any ideas would be great.

The laptop has slowed a bit and when i try and use vertain programs like photoshop i get a message to say not enough memory.

I only have around 2gb of images and 1 gb of movies on the laptop so not sure why the disk is so full. I have tried the disk utility but the only freed 500mb of space.

Thank you to anyone who can help

So you have your system install, 2 GB of Pics an 1 GB of Movies on it, that's it?

I'm sure you have any more files on your laptop taking up space!

You already admitted that you are not a Mac expert...so try a bit harder to find some files to delete or backup.

What about music files, videos, photos, programs that you installed & don't use...there's got to be plenty on there.
