A good way to consider for starting your gradual grade with plywood would be the cookie cutter method of benchwork. It will give you no bumps at the transition and allow for an easment grade before your 2.2%.
As for the S area, just find the elevation points at key points and regular intervals. Build these to those heights and the grade will have to follow. You can see what I mean as on this fine Nolix RR <!-- m --><a class="postlink" href="http://www.cmrailroad.com/Layout.html">http://www.cmrailroad.com/Layout.html</a><!-- m --> . This should solve Q 1& 2. Be sure to have one good benchmark and think about using a story board or witness board
Off hand, your area looks too small for a nolix but that just could be me and no longer familiar with N Scale
