Fred, good on you for your search, find and ask. Collect all the info you possibly can, listen to the experienced, learn from their "Opinions" and/or mistakes and heed their advice. But, all in all it will be what you make of it. Don't go in expecting to get new teacher of the year accolades. Teach and/or babysit your students as the situation pans out, but, most importantly, enjoy the experience.
Nothing ventured, nothing gained.
Good Luck.
