You seriously need to redo the personal statement, and rewrite the essays. my personal statements all basically said the same thing, but I created three different stories for them.
I also was told to get more letters of rec. I had four submitted, and since some schools use the prior years application, when all was said and down, I had ten LORs (all were good LORs too, all my writers let me read what they wrote, even though I waived my right).
Rewriting shouldn't be a huge deal, you've done it once, just think of new ways to say what you want. Start now and apply early too.
