Firstly, I think you are getting confused with the two types of memory a computer uses.
The 2gb memory you mentioned is the RAM - a small bank of solid state memory used by the computer to run programs, you already have the maximum your computer can take installed, so cannot upgrade further, but typically when you up the RAM, your computer will be able to process data faster.
Hard drive memory is the second type, and the one you are having problems with at the moment. this is typically a lot larger than the RAM, and is what is used to store data on, so all your music is saved on your hard drive.
What you are needing is a larger hard drive, so you can store and access more data. This can either be done by installing a larger hard drive (your macbook will likely have something like 80gb, so you could swap that drive for a larger drive like 250 or 320gb with a little knowhow (or paying a pro to do it)
The simpler option is to use an external hard drive - you can store your data on teh external drive, and just plug that in when you need to access it.
Time machine is not really designed for what you need - the aim of time machine is to copy yoru entire system, so if your computer fails, you can reload the whole lot from the external drive and revert back to your last setup (programs and files and so on). What time machine does not allow though, is an easy access to your files. All you need is a standard external hard drive (not formatted for time machine) where you can copy your data across to the drive, and once it is saved on the external drive, delete it from the computer, and when you want to access it, plug in the external drive - basically exactly the same as you would use a USB memory stick or floppy disk.
