To add links, sign in as the administrator, go to Components then click on Web Link items in the drop down menu. That will take you to the Weblink Manager. Once your on the weblink Manager page click on the "new" button in the upper right hand corner, fill in the details, click save.

You might want to add a new category before your new link. Do the same as above except click on the link for web link categories.

For the contact us page, in administration go to components, then contacts and click on manage contacts. Since you are new to this there should be only one contact on the page. Click on it. Fill in the info. Click save.

If you have any more questions feel free to contact me.

Good luck!
