Getting the most out of my diet....

I have been eating Vegan/and about 95% raw since Jan 1 2011.  I learn a little at a time.  Currently, most of my diet is liquid. 

I am loving juicing!  I juice everything...almost.   I noticed that spinach, romaine and kale produce less juice.  I continue to juice kale...but I have been making my shakes with spinach so I might get more out of it...and just use romaine for salads.  Is this silly...or am I doing a good thing. 

ALSO, I don't love the lemon in the juice, so I use a small orange instead.  Is there anything wrong with doing that?

I have been using powdered protein too.  I love pea protein best.  It is not raw though.  After reading China Study, Engine2Engine and watching Forks Over Knives...I am thinking that I may get enough protein without it.  Brendan Brazier uses hemp and rice protein, I don't love those and would rather go without, especially the rice...Are there any opinions on this?

I know this is a lot.  Thanks for reading and thanks for any input you can offer!
