Help on Modification to Form

I use this on in the header of my site to login and logout. It works fine but I want it to replace the username and pw box with links for “site admin” and “logout”.

<form name="loginform" id="loginform" action="http://seahamharbourboatclub.com/wp-login.php" method="post">

<input value="Username" class="input" type="text" size="20" tabindex="10" name="log" id="user_login" onfocus="if (this.value == 'Username') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Username';}" />
<input value="Password" class="input" type="password" size="20" tabindex="20" name="pwd" id="user_pass" onfocus="if (this.value == 'Password') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Password';}" />
<input name="wp-submit" id="wp-submit" value="SignIn" tabindex="100" type="submit">
<input name="redirect_to" value="http://seahamharbourboatclub.com/wp-admin/" type="hidden">
<input name="testcookie" value="1" type="hidden">

</form>

This is my website >
