Well first for the good news. You are right, SVSPX is a great choice. And the even better news is that it's expense ratio is 0.17%: which is even better than you listed. That's where the bulk of your money should go.
The bad news - I looked at the fees for all your funds, especially the front-end loads. PPTAX, ACCAX, ACOAX, ACVAX, ALTFX, and OPPAX all have front end loads of 3-6%. That means that for every $100 you invest, they take $3-6 right off the top and invest the remainder. I would avoid investing in those, that's just highway robbery.
Now there's a lot of questions you have to ask about what you want to invest, the basic being what you want your asset allocation to be. But assuming you're a long ways from retirement and want to go 100% stocks, here's how I would allocate it:
SVSPX: 55% Large Cap
ARGFX: 15% Mid Cap
PASSX: 15% Small Cap
OPPAX: 15% Int'l <---Only existing investment, don't add to it
You are missing a good international fund to invest in, since both of the Int'l funds carry large front-end fees. But since you have already paid those fees for the money you currently have invested in them, I'd leave it invested there. As you add new money to your 401k, I would invest it 60%/20%/20% in the three funds I listed and let your international exposure slowly dwindle. It's not worth losing 5% off of the top to get more international exposure.
There's arguments to be made to tweak those allocations a lot of different ways. If anything, others would probably suggest you invest more in the S&P 500 fund. I wouldn't argue with anyone that wanted to go up to 70% or so of their money in SVSPX. I'm sure there's some people on here who would go close to 100% in it, but I would suggest having more diversity and getting some exposure to small and medium size companies. Lastly, you are currently invested in JABRX, which invests 40% in bonds. If you wanted to have bond exposure, you could do it there or in the money you have invested in PPTAX, which is 100% bonds.
