How should I go about using an external hard drive for Time Machine and other things?

I have a Macbook and a new external hard drive. I'd like to set up Time Machine, but I don't want to devote my entire new hard drive to back ups. I'm new to this, but I think I want to partition my drive- how do I go about doing that? And how large of a partition do I need for Time Machine?

My Macbook has a 160GB hard drive, of which 84GB are used. The new hard drive is 640GB, so using the entire thing for Time Machine seems like a bit of a waste. I'd like to also use the hard drive to store large video files, which are eating up my laptop's drive at an alarming rate. My questions:
-What is the minimum amount of space I should allot on the new hard drive to Time Machine? My impulse is to divide it in half, which would leave Time Machine 2X my laptop's storage to work with, but I have no idea if this is far too much or far too little.
-I understand OSX has a built in drive formatting utility. Is this the best way to partition my drive? If so, um, how do I actually use it?
A few notes: I am not set on partitioning my drive, but from what I've seen on Apple's site, they intend you to devote an entire hard drive to Time Machine. If you can use a hard drive for Time Machine and also store other stuff on it, well, yay! I just don't want to do my first back up to discover that I'm wrong, and have to start from scratch.
I'm not really looking for other backup programs. I like that Time Machine is easy to use, built in to the OS, and automatic.
Anyone have personal experience with this? My googling and time on Apple's site have not been terribly helpful.
