Salubri,

I agree with problem 1 as to why he didn't go then.

For Problem #2 I just reread chapter 398 and in fact he knew who Isshin was, due to the look they gave each other after Isshin headbutted Ichigo. He just didn't know that Isshin was Ichigo's father.

Also I think it's why he waited to appear until after all the Gotei 13, were out of the fight to appear in the fight with Aizen. So nobody would recognize him. I also think once Aizen was beaten, Isshin made a quick exit so nobody would recognize him.
