As somebody who overcame heavy disciplinary action to get into some really great schools with really great offers, the best advise I would give to anyone is as follows:
Disciplinary action and applying to law school is quite analogous to being a professional athlete who faced disciplinary action.
If Albert Pujols were arrested today, and spent the rest of the season in a federal prison (but was released next year) would this influence his contract for next year? The most likely scenario is yes, but it wouldn't influence it too much. He would still likely be the highest paid first baseman in the league, but he might not receive the record breaking contract he seeks.
In the NFL, Vick's "baggage" certainly played a role in his only receiving a one year offer. That said it is still an above average contract for a starter, and there were other factors involved (older, being injury prone, etc.) Further, his actions greatly angered the public, and might actually drive some fans away where as a law school applicants baggage is likely under the radar - i.e. the law school isn't hurt. Still, no one will argue Vick would not have made more money had he never went to jail.
So the answer is yes, there will be an impact on applications for your misdemeanors. Some schools will flat out reject you, because of them much like some professional sport teams flat out reject a player who has some character concerns as it goes against their team philosophy. However, this does not mean you'll automatically be shunned out of the t-14. The fact is you won't be. Different schools and different evaluators have different philosophies, and there's nothing like "this is Columbia - we only accept students who have not had legal trouble." This is much like how some top sport franchises won't take on character concerns, while others really just evaluate the athlete as a player on the field.
Also, like sports talent does supersede character. There are many great character ball players who can't get a job, while Ray Lewis who may have killed a man was the highest paid defensive player for a while after this - nobody mentioned what he did as all they could focus on was that 2000 superbowl. Law school is similar. Just like how that great applicant who saved orphans and started a charity with a 2.5 and 145 will get rejected from School A, an applicant with a 4.0 and 180 who did something egregious will likely be too good to pass up.
Of course, people change and with the exception of a school like an Illinois who is vocal in saying they want people who have made smart choices from a young age, most do forgive mistakes if they believe an applicant really changed. A player like Josh Hamilton comes to mind as someone who made some pretty egregious mistakes, but nobody would argue his past crack addiction will stand in the way of a 20 million dollar contract (his back problems might!) Rather, some teams might even see his journey of overcoming his drug addiction as a great marketing ploy, and many fans like him more because of it - if anything he's at least more interesting, a trait that top law schools favor a great deal.
