Although I've never really used sneak, lockpick or steal, this is what I've noticed so far. First of all, sneak is next to worthless ATM. I'm guessing it was just overpowered heavily so it got nerfed. Lockpick I'm sure has it's place, but from what I've seen, there aren't very many containers/doors to unlock around the game. Not to say that there won't be, but right now your options seem fairly limited. Steal can actually be quite useful if you get away with it. People will not like you very much, but hanging around in NCR I've been stolen from many times. If successful, you can steal plenty of good items from people, but beware: if you fail while in a guarded town, you will be flagged and anyone can kill you. As far as stealing from NPCs, someone else is going to have to fill that in because I know at some point you could steal from just about any NPC but I think some things have changed. Science is mostly used in harvesting/crafting so if that's the path you want to take, you should invest some points in that.
The SPECIAL stats you've shown look a lot like a gun character. Actually almost exactly like the one I made today. You should be able to get most good gun perks like bonus rate of fire (which is currently not working, but should be eventually), weapon handling, and bonus ranged damage. I think you can also get lifegiver and toughness, which will help greatly if you're a PvP character.
Your strength will only affect your hit % on guns that require a ST more than 3, which is a good number of them. But high skill or weapon handling perk will take care of this.
6 EN will give you a good hp when you reach lvl 21 (the level cap ATM).
3 CH is the minimum to talk to most traders, which is fine. The only other place CH is used afaik is when leading people in a group, and with three, you should be able to take two other people with you.
