For the scrolling issue, you can disable some elements that you do not need with TMSFMXTableView.ItemOptions.
And decrease the BufferSize, so the scrolling is faster. The Buffersize and other performance related tweaks are explained in the documentation.
To disable the header / footer you need to edit the custom style and set the header.visible to false and the footer.visible to false in the StyleBook editor. This is also explained in the documentation found on http://www.tmssoftware.com/site/manuals/TMSFMXTableViewDevGuide.pdf
