turn signal flash really slow ...

Also one bulb out or in wrong (they only go in one way but the sheet metal socket can be forced...) will change the current draw.
Off the top of my head I beleive the bulb # is 1034A for the fronts, 1034 for the tail/brake/turn.

To begin diagnosing, test everything and take notes. Flashers, turn signal, and parking-tail lights. And if need be brake lights. The you can start to figure out relationships of what is not working and what is.
