Troubleshooting Calibre Settings to replicate Amazon store settings?

[kdwosk]

I have a Kindle 3 wifi only. I am new to the Kindle and Calibre. My goal is to have Calibre convert ePub formatted books to MOBI in the exact format that books are in on the Amazon store. I used the CSS settings that were given in this thread
https://www.mobileread.com/forums/showthread.php?t=40359

.calibre1 {
margin-left: 0pt;
}
.calibre2 {
margin-left: 0pt;
}
.calibre3 {
margin-left: 0pt;
}
.calibre4 {
margin-left: 0pt;
}
.calibre5 {
margin-left: 0pt;
}
.calibre6 {
margin-left: 0pt;
}
.calibre7 {
margin-left: 0pt;
}

and it fixed the margin issues that I was originally having. The other issue that I am still having is that the paragraph indents are too indented. This is the only other issue that I have come across so far.

Does anyone know or have CSS override code or another method that would allow for the the exact same look and feel as books from the Kindle store ?

Also, would another program better meet my needs?
