Oldsmobile/Buick Repair: car wont start/service engine soon, car down, olds intrigue

Question
Okay, so I don't know anything about cars, and I'm practically desperate... I have a 2000 Olds Intrigue, V6... and for the past week or so, it's been slow starting (but it would eventually start), and twice it hasn't started at all.. it just makes the clicking noise and that's it.  The first time I was able to give it gas, and it started, but it happened again last night.  Also, when it does run, it always says "Service Engine Soon" and I really don't have any resources to take my car in to get fixed, so I was wondering if there was anything I could do to hold me over until I'm able to take it in?  Thanks...
