First and foremost - you get into law school with a high GPA. Admissions is slightly more forgiving if you went to a super undergraduate school and/or if your degree is in math, science, or engineering. Still, before applying, do whatever you can to boost that GPA. When researching schools, take their median GPA accepted data seriously.
Second is you LSAT score - it needs to be high - and it needs to be really high to get into a top tier school. Admissions treats your LSAT and your GPA like a composite score. If you ace one, you can do slightly less well on the other. Institutional scholarships are awarded almost exclusively on these two factors. So, prepare for the LSAT. Take a course if you need to. They are expensive, but most of them come with money-back guarantees if your score doesn't improve. If your score isn't what you want the first time around, take it again, but only once you are absolutely sure that the score will improve.
Unfortunately, your resume and your recommendations will mean very little, especially at the top schools. I have seen people who have worked in serious positions at the White House get rejected from schools I thought were within reach. Unless you are a Rhodes scholar or something similar, your resume just isn't going to pull a whole lot of weight.
