What is the difference of the 10 commandments from other Biblical laws? What distinction do The 10 Commandment have over other rules in the Bible?

Is breaking any of The 10 Commandments an immortal, unforgivable sin while other sins are not? 

I just want to know the difference; why is there in a "top 10" list?
From a Baptistic perspective, there is very little difference between the 10 commandments and the other 603 rules and regulations of the Torah.  Note: I'm specifically not addressing the extent to which the law of Moses still applies, as it is well covered elsewhere

While the 10 commandments are a succinct guide to right behavior, their popularity really only stems from that point.  Taking a step back, most of the other Torahic Law deals with ceremonial functions - and if its choice between remembering "Don't Steal" and whether one needs to present a bull offering or a grain offering, which one would you promote?  Likewise, the priest needs to know what's leprosy and what not, but "Don't commit adultery" has a much wider applicability. 

A cursory reading of Leviticus will show that the bulk of the Torah concerns not how a person should act, but rather what kinds of offerings and atonements should be made to resolve things.  Sure, there's the ScapeGoat, Baldness, rules about what does and does not constitute incest - but there's actually far less about personal behavior even in "the Law" than you might expect.

Indeed, when Jesus was asked, what is the most important, he didn't say "the 10 commandments."  Rather, 


  Matt 22:34 Hearing that Jesus had silenced the Sadducees, the Pharisees got together. 35 One of them, an expert in the law, tested him with this question: 36 “Teacher, which is the greatest commandment in the Law?”
  
  37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ 38 This is the first and greatest commandment. 39 And the second is like it: ‘Love your neighbor as yourself.’ 40 All the Law and the Prophets hang on these two commandments.”


His answer reflects several established Talmudic traditions:


The Schema (Hear O Israel, the Lord your God is One) is the primary law.  Everything else stems from it.
The 10 Commandments themselves divide neatly into two categories:


the first 4 (in Protestant numbering) are about how you love God (No other Gods, idols, No Blasphemy, Sabbath)
the other 6 are about how you love others (Don't steal, lie, kill, cheat on your spouse, covet)



What Jesus did was to emphasize the fact that love undergirds all of this.
