Well, ABS light, u might have to take it to a shop with the proper equipment to look into it, probably will charge you. Unless ur ABS fuse is blown, check inside the fuse box.
As for the brake light, you can figure out where is it coming from. 3 things that can turn it on,
Parking brake - make sure it is fully released
Brake fluid low - Check level, and Unplug the switch, cycle the key, see if light goes away.
ABS module request - Unplug the ABS module, cycle the key, see if brake light remains ON, ABS module is below ur Brake Fluid reservoir.
All of above are simple task you can do, other wise, u'll need more tool for the job. Brake is #1 safety item, Don't ignore it! good luck.
