Help! questions for reapplying

Hi,

I submitted my application pretty late last year (primary submitted in August, finished most of secondaries in Sept - Nov)
I got one interview but did not get in-
I have 3.9 GPA and 8 V, 11PS, 13BS, M, (32M) and I am from CA.

I am thinking of re-applying this year.(don't think I will re-take the MCAT, because my verbal score is stuck at 8)
And I have few questions...(any input will help~)

1)When you re-apply to same schools, do they look at your previous primary (or secondary) application?
Does that mean that I have to re-write everything?
(I will update my work/activities and personal statement, but I don't think I can change a lot - If I need to make a lot of changes, it will take a while, since I am not a quick writer)

Or will it be better to apply early with similar essays from last time?

2)I applied to ~ 20 schools last year, but ended up writing secondaries for only ~12 schools. (because I could not finish all the essays by the deadline) Will the 8 schools that I did not submit secondaries still have my files?

3)When you apply to same school the second time without much of new materials (activities or personal statement), will it be bad? (But I still want to give a try for UC schools)

4)If I have same LOR, will it look really bad?

5)Do you have any good suggestions on schools? (when I applied the first time, I only applied to schools with 32MCAT or lower except the schools in CA, will there be a chance if I apply to OOS schools with MCAT ave higher than 32?)

Thank you so much!!!
