You'll enjoy camping on McIntyre and Robinson, both super lakes.  And Suzanette is outstanding as well.  I've been through all the areas to/from PP to Brent and Suzanette over the past couple of years.  You may want to consider heading north through Isabella Creek or Nest/Point and then to McIntyre via Sarah.  Then come back via Cecil, robinson and Kett.  Only reason is it's a bit quicker to get to Suzanette that way and coming back you'll have a much lighter load.  The portages between Kett and Basswood are not bad, just long.  And the portage into the unnamed between Kett and Nub is short but really steep.
