wow, sounds like the car had a heart attack. anyway, the service engine light is a fuel control issue. the yellow abs light is a problem with the anti lock brake system and that will disable the traction control as well. take it somewhere and have it checked for codes to see what area you need to look.
If you just bought it, is there any warranty??

Probably an Alternator problem. I have seen this a number of times where all the dash lights come on and it's just the Alternator. Check this first.
