there's no reason at all to have Aaron, Kaline, and Banks rookie cards left unslabbed, no matter what condition. My first submission to PSA had all those Topps cards (minus the Aaron). Most came back as 4 and 5's but my Williams came back a 1. Completely worth it in my opinion. The others are probably worth it as well. IMO.
I'd slab all of the '54 rookie cards, Mays, Robinson, Williams yellow), and any other stars that you think would grade a 5 or better. I wouldn't bother with slabbing any of the cards with paper loss.
