I'd like some recommendations on my stats. At the moment I'm planning on this:
STR 3
PER 4
END 4
CHA 8
INT 9
AGI 6
LCK 6

Main idea is to make her a small guns/speech/follower leader with good charisma and lots of skillpoints.
For implants maybe END,STR,CHA and one other.

You will lose out on an epic number of perks with STR, PER and END that low. You will also will not be able to use half the implants. If you want to roleplay a charismatic character, more power to you, however even with what you want to do charisma is terrible. Some of the perks you'll lose access to are Strong Back, Weapon Handling, Better Criticals, Toughness, Solar Powered, Life Giver, Long Haul, Stonewall, Lead Belly, Slayer, Nerves of Steel. You're going to have trouble using a lot of guns and good luck carrying anything until you get those companions.

3 Strength will be extremely annoying, and you won't even be able to use most guns proficiently.

I'd drop a point of agility or luck (unless you want to gamble) to get 4 in STR.

Also pick four eyes and get some glasses, plus a cowboy hat, for extra perception.

Doesn't STR only effect large weapons though? I won't be using those.

No all weapons have str req. Rifles typically require 3 - 5.

1 implant for per point of END, so plan accordingly.

I go INT of 10 and usually drop 1 AGI and 1 LUCK for +1 to STR and END
