They should come into your template files automatically if the import was successful. Have you chosen a Theme? Did you test drive the theme before the import with test posts to make sure the site was working?
To check to make sure that the import worked, check your Administration Panels Manage Posts screen to see if there are posts listed there.
If they are not there, then open your database with PHPMyAdmin and look at the wp_posts table to see if the posts you imported are there and in the right fields. It takes a minor glitch to mess up the order of the import, putting all your posts in the excerpt field instead of the post field, though the import_blogger.php is really good at fixing that.
If they are not in your database or screwed up, then you will need to empty the database and start over.
Start by importing 4 or 5 posts at first to make sure that it is working, if possible.
