From my research, the best place to get Omega-3 & Omega-6 fatty acids (both are needed) is with Udo's Oil Blend.
Essential Fatty Acids, Omega 3, Flax Seed Oil > Udo's Choice™ Oil Blend - the RIGHT FAT DIET!
Udo Erasmus is like the father of Essential Fatty Acid research. It is mostly because of his work that we even know about Omega3 and 6 fatty acids. He was crusading to bring attention to these two essential fats, while the rest of the world in the 80's and 90's was on the "NO FAT" fad.
I buy his oil from a health store. I get the little bottle and put it into my shakes or pour on my salad etc. It goes bad after 3 weeks so don't get the big bottle, unless you have a bit family.
As for calcium, I am not 100% sure yet what's the best supplement. My naturopath has me on a liquid one that combines calclium, magnesium and vitamin D at the moment, but it's not long term. Long term I think the plan is for me to get all my calcium from veggies and nuts etc.
One thing I can tell you for sure with calcium, is don't bother with dairy, but you already know that I bet.
