For the blinkers, it soulds like you have either a dying fuse or a dying relay, check both.
For the brakes, as mentioned, go in an abandoned parking lot and try a suicide stop and it you feel the brake peddling pulsing, your brakes are OK and you don't need to worry too too much. Check and make sure your brake fuild is topped off and your drums are OK.
Our gen Rangers do have some weird problems, but not as bad as other cars.. My sister's bowtie Corsica's cassette player will slow down/speed up as your accellerate/brake... Rather odd, really.
