Sheet checks out. Initiative should be +2 (it's a Dexterity check, but no skills apply, so you generally don't add a proficiency bonus) and Strength 8 by my count.
In the events so far, the group has been hired by Gundren Rockseeker to escort a wagonload of supplies to Phandalin while he rode ahead to prepare things. They got ambushed by a band of goblins on the way, but made it to town alive and dropped off their supplies where they belonged. However, Gundren and his bodyguard have yet to arrive in Phandalin, and their horses were found on the road, killed by the same goblins a day or so back - implying they may have been captured or worse.
Phandalin is essentially inspired by wild west frontier mining towns. I'd like all characters to have some tie to Rockseeker, so perhaps he hired you to come to Phandalin a couple days ahead and keep your ear to the ground, make friends, act as a sort of PR? Then Barthen, who runs the general store and is Gundren's primary liaison, could hook you and the others up quickly for consulting on the disappearance of your employer.
