This type of question is too general, as this site is aimed at more of a question by question basis, we tend not to try and ask a question that would be too long or more like a tutorial, but instead direct you to the howto's or the site, in this case would be
www.xfree86.org as they should have documentation on installing X. Then from that point, when your installing and have a question, then ask it here.
Telling you how to install step by step in a tutorial situation can take forever.. and too much typing for most, and would be pointless if there are howto's and tutorials out on the web already that would walk you thru this process.
