a few beginner-intermediate questions

1) the shorter the board the closer you need to be to the peak, and the steeper the wave needs to be?
(I notice most short boarders seem to sit closer to the beach than me, they don´t even bother chasing the "longboard" type waves)
(and they seem to favour the steep gnarly waves that I tend to avoid)
1b) corrolory of 1, of sorts: if you´re on a longboard, the closer you are to the peak, and/or the steeper the wave, the harder it is to catch the wave without wiping out?
(i notice sometimes the tail of the board lifts up, pushing the nose down and I nosedive)
2) Today was an onshore breeze (10-15mph according to surf forecast), and it seemed harder to catch the same size of waves I was catching yesterday on a glassy day. Harder to catch waves with an onshore wind?, and the more onshore the harder it is?
