What exact code is needed for Wordpress/Woocommerce login/sign up pages

Question

I am creating a small e-commerce website using wordpress & woocommerce but I'm not really understanding the login/signup abilities for users. I just want users who visit the site to be able to click a link on the home page where they can sign up and login (with the option to reset their passwords) and in return those customer details are saved within the user data for the wordpress admin to be able to see. What is the coding for this? Because I can't seem to get into a lot of these plugins.

<?php 
  global $wpdb, $user_ID; 
    $firstname='';
    $lastname='';
    $username='';
    $email='';

    //if looged in rediret to home page
    if ( is_user_logged_in() ) { 
        wp_redirect( get_option('home') );// redirect to home page
        exit;
    }

    if(sanitize_text_field( $_POST['com_submit']) != ''){

        $firstname=sanitize_text_field( $_REQUEST['com_firstname'] );
        $lastname=sanitize_text_field( $_REQUEST['com_lastname']);
        $username = sanitize_text_field(  $_REQUEST['com_username'] );
        $email = sanitize_text_field(  $_REQUEST['com_email']  );
        $password = $wpdb->escape( sanitize_text_field(    $_REQUEST['com_password']));
        $status = wp_create_user($username,$password,$email);

        if (is_wp_error($status))  {
             $error_msg = __('Username or Email already registered. Please try another one.','twentyten'); 
        } 
        else{
            $user_id=$status;
            update_user_meta( $user_id,'first_name', $firstname);
            update_user_meta( $user_id,'last_name', $lastname);
