Just Installed 2.0

[TheLookBook]

Had to apply a new theme after installation advised by support here but no problem. Now using the classic next generation and love it. Need help removing the SMF logo and the lettering surrounding the page. Just want a good clean white background around my graphic/ logo. Also, my member count went down 2,000 after installation but when I use the old classic theme the count is correct. Furthermore will the adk portal work well with 2.0 See attachment please. Thanks for your help.
