Outlook 2007 contacts / Word 2007 Spacing

[Wires]

If anyone could help me out it would be appreciated.

1) I use Outlook 2007 for my company on both my laptop and desktop. Overtime I've been adding contacts to both computers. I would like to ensure that both the pc and notebook have the complete list of contacts and contact info. I could go through and add each to the other one at a time manually but I'm sure there is an easier way.

Is there a function that will allow me to sync my contacts between the two computers?

2) I think Word 2007 operates differently in how it handles spacing. Everytime I hit the enter key it reacts as though it is a new paragraph and double spaces. I've figured out how to change this on a document to document basis (Line Spacing > Remove Space After Paragraph) but I would like to set this as the permanent default but do not see an option for this. I've read a little online and they talk about having to edit the normal.dotm file however I cannot even find the file (I'm using XP if that matters). It doesn't seem complicated but I can't seem to figure it out.

Thanks.
