i think i wont advice you what to make, better will suggest what not to :>
So if you are make small gunner 5 strength is enough, since only tommy gun from sg requires 6 strength, its not likely you will use it anyway.
Dont know if you want to be sniper or burst with weapons, but you can still raise your perception by drugs, just i suggest you to have 7 since you will probably need it for good sg perks (bonus rate of fire, sharpshooter)
Charisma - if you want others to talk to you take 3 charisma, 3 and 4 are quite same, just you can lead 1 more people. But if you want to be better in combat you should consider having 1 charisma.
I suggest having 6 IN since it is needer for some perks you might take as well.
And as said before agility should be even number. If you want to be sniper you should probably have action points for one sniper rifle shot, so you will need 8 (and thus 6 agility) you can also use drugs such as nuka cola and jet to get 2 aimed shots in a row :>
And if you are going for sniper then i recommend you having 10 luck.
And if you want to take one handed and use only one handed weapons then you should take 4 strenght. Otherwise dont take this trait. And i wont advise you to neither take or not to take finesse it can be object of discussion if its good or not :>
And skills you want to tag should be tagged according what you want to do in game. Do you want to have gunsmith level 3 or etc.
