I am an outdated head programmer/deisgner, but new to wordpress/css.

Web page to glance at: www.starfightergeneral.com
Concept: X-Youngster

Reward stuff I am seeking to add finally:
Graphic for the scroll icon.
Parallax background picture scrolling.
Far more posts exhibited to about 10.
Generating the web site by means of previous content interesting to simply click on.
%Scale all button measurement.
And of system typical suggestions.

Any assistance would be appreciated.

Thank you,
Jim
