FCW, LDW, stability, abs lights came on all of a sudden

Sitting in line waiting to get a coffee and the FCW, LDW, stabilility and ABS lights came on... car still ran fine, but would like to get this taken care of. Prefer to do my own work if possible, but know my limitations.. Any suggestions? I've read some of the battery / connection / alternator answers... couldn't really tell if those took care of it or not.. Will appreciate guidance.
