Problem with login, view function and image

I have problems with my forum started from some simple tutorial. Its made from begining not SMF or vbulletin.
First problem is that I have login script but I would like that after loged it will show user panel instead of login form. Like here on this forum.
Second problem is that I have only option to add topics. I need to add forums and groups. I made already page but I cant add another group of forum. Also posts/replys arent counting(so its 0/0).
And third, I dont know how to draw text on image to hide those numbers on the left(ID).

I made picture of site is on bottom of the topic, becose I dont whant to have spam.

Well I made two pages with adding forum. First page is forum view, second function of it. I know name files are stupid but I will change that. Heres files code:
**forumadd.php

echo "<a href=main_forum.php>View your topic</a>";

I know why it looks like that and it will change. I just need the proper fucionality.
