Greetings all, first post from a former 145 captain with 5K hours in the airplane. Flaps 45 IS the standard config for almost all landings.
No slats, so normal pitch attitude is 0-1 degrees nose-up with a normal flare attitude of 3-5 degrees nose up; having the jet's nose 10 degrees in the air is nowhere near the standard. Tailstrike occurs at between 11-13 degrees body angle. To say this FO was an idiot and the Captain was not any better is an understatement.
Unfortunately the pay offered by US regionals, coupled by the experience requirements for hiring that were ridiculously low for a few years, has led to a situation where you have many 22-23 year old kids straight from the "me generation" who have not worked for the position, and view the jet as a big Nintendo game to entertain themselves with. Most of them then decide that since the company will not pay them as professionals they have no personal desire or obligation to fly or conduct themselves as such! (end or rant)
