I've been looking at this stuff all day too, and I originally thought slug 4 into each and just go from there, but I've decided similar but not exactly in line with what you've got.
I do think having enough CHR to build settlements will be both interesting and worthwhile.
What I'm closing in on is something like
S -1
P -4
E -3
C -4
I -5
A -5
L -6
Then I'll get the bobble heads for STR, CHR, INT, AGI, and LCK and plug a level point into STR, CHR, and LCK so that will unlock Armorer, Locksmith, Pickpocket, Rifleman, Toughness, Lifegiver, Local Leader, Medic, Gun Nut, Hacker, Scrapper, Science!, Gunslinger, Commando, Sneak, Action Boy, Moving Target, Fortune Finder, Scrounger, Bloody Mess, Idiot Savant, Better Criticals, Critical Banker, and Grim Reaper's Sprint, with only having to sack three levels worth of perk points to SPECIAL stats and that seems to be a lot of the best shit for a shootan and lootan play through.
If I want any of the highest tier perks I'll just sink perk points into them once I've maxed out all this stuff.
