Re:Looking for a little guidance re Starting Strength by Mark Rippetoe
Well your abs will be getting worked more in that routine than most other routines you could think of. Squats, Deadlifts, OHP and Power Cleans all work your core to shreds (the primary function of the abs is to stabilise the spine) and you're doing these movements very frequently. I wouldn't be worrying about whether you should include more core work, I'd be worrying about whether you'd be able to!
Calves will get worked plenty from squatting and power cleaning.
As for your arms: Your triceps get worked plenty, overhead pressing and benching hit them, but your biceps don't receive a massive amount of direct stimulation, but if you are worried about this then you could do the variation of SS that includes Chin Ups? And obviously it wouldn't hurt to do some sets of curls if you wanted, but I wouldn't go overboard. As the man himself says "I don't recommend you doing curls on this routine, but we both know you're going to do them anyway"
