Sounds like a good idea.
The MOST IMPORTANT ones are, like I said, a strong multivitamin/-mineral and a high dosed EFA. PAK and OMEGA give you all the essentials you need.
For protein I would go with a whey ISOLATE. Universal has got ULTRA ISO WHEY.
Everything else is just icing on the cake. Spend your money wisely. Food over pills and powders. Period.
