how can i set site menu on top because its now on the left and i don't want it there (if thats even possible?)
First of all, creating similar threads is against forum rules and next time you will be reproofed.
I might suggest you to use your menu code, which you can see in CP->Site menu builder (at the top. It looks like this: $SMENU_1$). See more about Site Menu builder here: http://forum.ucoz.com/forum/8-5638-1#26197
Once you have this code - embed it into the template, in the place you want this menu to appear on your website. I might suggest “Top part of the website” template.
How can i delete the background of the forest
This is a very difficult task as the background in this design consists of many pieces. It will be easier to change the design all together.
