Highway rest areas, truck stops, some WalMart or other 24 hour superstore parking lots are generally hassle free places to park and sleep for free (if you sleep in your vehicle). County and state parks or forests are good, if you sleep during the day and have the proper sticker on your vehicle but you still can't put up a tent. The exception would be if you have a hammock like a Hennessy, then you can usually get away with guerrilla day-time camping and not worry about your vehicle being towed (make sure you're out of the park before closing time).
Truck stop showers can get pricey IMO ($6-$15) but in many areas, if you speak a little Spanish, you can ask maids at motels to allow you to use a room's shower before they clean it (free-$5). A basic free (hardship) membership is available at most YMCAs (just ask) and many times they'll allow stranded travelers to use a shower for free.
Temp work of all kinds is available in most cities and fast food places everywhere are usually looking for help regardless of experience. (Edited to add:) Any income is better than no income and a late shift gig at a fast food place doesn't interfere with the search for something more suitable. Although I don't advocate lying, there is no law that says you have to tell prospective employers that you are currently flipping burgers to keep body and soul together.
Stay clean and presentable, maintain a positive, friendly attitude and you'll be fine until you're back on your feet.
