Sorry, Plumber,
not that easy. You need a balance chart worked out for your specific aircraft, with the designated body stations measured out. However, When you buy/lease your AC, the seller/lessor will provide one. When applying for an AOC without AC, simply point out that you have not specified the actual AC just yet, but the WB forms will be supplied when you add the AC to your AOC.
As for weightsheet, just iata standard.

Edit:
just saw that you wanted the WB process. You'll probably have to buy the manuals from an operator. I know I would get in trouble if I sent out one from my company. Again, contact the lessor/seller, they have one.
