Ok time for sparky to speak
Looks like a CH (Cutler_Hammer)panel.
A recent upgrade to the panel would make sure it is grounded per NEC but just because a panel is grounded, does not mean that everything leading from it would be. In the case of a older home that utilized k&t or the old cloth romex, there would be no grounds on the outlets. Some of the romex may have had a ground wire in it and when whoever upgraded the panel, they hooked these wires up. Nevertheless, no real cause for concern here. If the two prong outlets are not used for appliances, they can remain ungrounded. Otherwise recommendation that a sparky comes around and provides grounding for those receptacles that would require such.
Single wires on a two pole breaker is not a bad thing but more so a incorrect thing. The breaker will still trip for if any side of it senses a overcurrent situation, it will trip. Why anyone would do that is beyond me. Perhaps they had a sale on 2 pole breakers. Either way though, my only concern would be that the wire is rated for the protection the breaker is giving it (ie 12 ga to 20 amps etc)
Nothing says you cannot splice in a panel although I am really against such. As Joe stated it makes it tough to troubleshoot but at least the sparky who did that upgrade made them visible.
