Have patience and understanding please am newbie thanks

Here goes
# I have created a webform for the site....have following questions related to that
1) How to modify the width and height for textarea...I have disabled the Resizable option by the user option(as I don't want this option for the user)....I have else where that if I enter Width and Height settings in the webform settings that a themes css settings can override it...hence the question.
2) How do I get it to display the webform on one page....currently it has a brief into and then has page 1 2 3 at the bottom....again not sure if its theme related or not
3) When the page gets published it makes itself the home page and overrides the current home page....any idea how to make it just a normal page?..

Cheers
