Formatting textField populated from XML

programming flash

I am populating the text of text fields with data from an XML file. I would like to do two things.
The code looks like this:

DSGbox.textFirstName.htmlText = xmlDSG.name.first;
    DSGbox.textLastName.htmlText = xmlDSG.name.last;

[LIST]
[]First, I would like to format the text… bold, font size, etc…
[]Second, I would like to concatenate the first and last name to appear on the same line without space in between caused by two text fields. I tried the following, but it didn’t work.
[/LIST]

DSGbox.textFirstName.htmlText = xmlDSG.name.first + xmlDSG.name.last;
