Ask questions on the ground until you understand, that is what ground school is for.
Go over the jump plan in your head several times (I did all the way up to altitude).
A couple of deep breaths right after leaving the plane to get over the sensory overload
Jump the plan (learn the hand signals and what to do to correct)
On final approach (into the wind), Don't look at what you don't want to land on or in look at where you need to go (we go where we look).
When ready to flair it helps me if I don't fixate on a spot on the ground but more towards a spot a bit beyond it as I flair. I don't fly to a spot on the ground so much as land on it (ok I try to land on it...usually end up by it somewhere).
Hope this helps.
