Car won't start! A 2000 Chevy Malibu, and is causing me to say things like...

[woaikonglong]

...son-of-a-bucket and what-the-fetch!? I have a 2000 Chevy Malibu, it has about 150,000 miles on it (business car in a previous life). It now won't start. It has been giving me problems for a few weeks now where it takes a while to start up like cars sometimes do on bitterly cold days. Either way it would try for a few seconds and then start. Today it started up no problem when I left for work at 3am, and only stalled out a second or two when I got out of work at 11, now when I went to go to the library, and turned the key: it clicked once and was silent. naturally the check engine light, battery light and oil light all come on, but that happens no matter what, just turning on the car, after a has stop... My "grease-monkey" self got out and checked the oil level, coolant level and the rest of my oils and additives. I have almost a full tank of gas. It is only a 1.5 year old battery. I can't think of what the problem is that it won't even try this time. Any ideas?
any way to check to see if it is a starter?
