Answer 1

Wordpress have pre defined variables, as

$cat

$tag

etc. you have to use

$author

to make your process.

Answer 2

what you are doing wrong is you are not using your get_the_author_meta() function in side the loop so you need to specify the author id.

either use the function in side your loop or use simple as below code

<?php 
global $current_user;
$current_user = wp_get_current_user();
$uid=$current_user->ID;
?>

change your function author meta as

<?php echo get_the_author_meta('first_name',$uid) ?>

for all your author meta for more help you can check reference code http://codex.wordpress.org/Function_Reference/get_the_author_meta
