Law School Discussion

I have been preliminarily thinking about possible topics.  For my safety schools I will plan to write a conservative, ordinary personal statement.  But for my reach schools, I am thinking of ways to grab their attention.  I have an Alcohol Related arrest which has since been expunged.  But an explanation at some point will probably be necessary in the application, so I have thought of playing the recovering alcoholic card.  I believe I can justify things such as criminal history and meteocre grades while presenting an intriguing story.  Furthermore, I will be able to touch on my weaknesses without highlighting them.  So even though I may be an alcoholic, I am in no means recovering.  Admissions doesn't need to know this.  But nevertheless, it can make for an eye-catching PS.  But the question I have is, will admission look down upon alcoholism?  Or will they accept recovery and see it as a positive attribute to my character?  I would appreciate any input.

I went to a university which gave out grade points as grades.  So when I received an A+, I received a correlating 4.0.  So when I received A's they fell somewhere in between 3.5-4.0.  But the LSAC scale seems to put me at a disadvantage because other's A+'s would be a 4.3.  Does anyone know if they account for this?  If they do, I would actually improve my stats. 

I have a 3.2 UG GPA and am set to take the LSAT's in June.  My practice tests have been steadily improving and I think a 160+ is a possibilty.  With these stats, what should my expectations?  I am hoping for top 25-100.  Am I setting myself up for a letdown?
