The skillset of a succesful PGY3 and 4

What is a "good" PGY3 or a PGY4 for that matter? I guess I'm wondering what I should be aiming for to feel confident in myself when I am sitting across the table from a prospective employer. I'd like to do inpatient and/or CL combo. Should I moonlight to sharpen the skills? Does moonlighting experience matter when I start looking for post-residency jobs? Part of me wants to, part of me does not because I enjoy my free time.

Good:
I've been fairly successful with my PGY1 and 2 psychiatry...
