4 VB, HTML and Template Questions

[H3C x Nevz]

1.When you go to a users' profile, it automatically goes to the first tab. I don't want to change that, I'd just like to know if there is a URL for going to a specific tab. Is that possible?
2. For some reason, my HTML isn't working for me. Below is a part of my postbit - could someone please show how they'd properly give it an orange border?

<if condition="$show['avatar']"><td class="alt2"><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl]" $post[avwidth] $post[avheight] alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="1"/></a></td></if>

3. Is there any way to add things to the middle of the postbit (the blank area between the avatar and all of the right-aligned info?
4. When I upgrade from 3.8.1 to 3.8.3, do I lose anything like mods or template modifications?

Thanks for all your help.
