Rich -

Since your trip will take you as far as Camel, here are some options for your return to PP (assuming you are doing the Metacryst, Baird, Cub, Eag route to Camel):

1) (longer) push from Camel to north to Fred, loop thru Heron Bay to Sturgeon and back east to Russell  or ...
2) back track to Eag and take the portage north to McDougall (its a bit sloppy on the McDougall end) or ...
3) back track to Baird and take the portage north to Keats (this portage is "entertaining", especially toward the Keats end)

Continue east down the poets chain to Kawnipi and then south to Keewatin.  Turn west and do the Williams, Payne, Hurlburt lakes to Trant.  From Trant

1) exit back toward Kash and return to PP the way you came
2) turn east and head thru a series of smaller (no-name) lakes to Silence

At Silence:

1) turn south and run the S-chain back to North Bay or
2) push thru to Agnes and turn south to do the Meadows portages

The Poet's Chain will give you a few waterfalls (more if you do the longer loop Russel/Chatterton/Keats).

The route from Keewatin to Trant has picto's on Keewatin, Payne, and Trant.  If you push east thru Silence to Agnes, you can paddle a few yards north and see another picto and a petroglyph and then snag the southern two on Agnes as you head toward Meadows.  (If you have time to kill on Agnes, you could also check out the 2 on the eastern arm of Agnes or even head north to the picto panel on the northern section of the lake.

I've done almost all of this padding solo at one time or another.
