migrating wordpress from local to web server issues

Hi

my case:
I created my site using wordpress locally on XAMPP, and now am struggling to get it up and running on live server! I tried all the options and visited all the forums.. until now none seems to know the solution.. hope u can help in this.

what I did :
after I edited my site locally and created pages and menus, it worked perfectly on my local computer.. now i want to upload it to the web host for http://www.tawasul.ps .. Here is the steps i did :

1- I exported the database from local machine into .sql file
2- I created a new database in the web server and gave it a new user
3- Inside phpmyadmin in web server, I imported the .sql file.. import was succesful.
4- I created a folder inside public html named it ar, then I uploaded my wordpress folder from my local machine to server inside ar folder using FTP client.. i created ar folder for testing to see if it works or not.
5- I went to wp-config and changed db user, password and host to my settings
6- I opened wp-options in phpmyadmin and changed site url to http://www.tawasul.ps/ar and did the same for home.

problems encountered:
1- when I open http://www.tawasul.ps/ar its not as it is in the local machine.. its missed up!
2- when I try to open wp-admin I get nothing.. as it is unrecognized link.
3- I noticed when I run xammp in my pc the website background change and few other things, also wp-admin opens (but the url in the browser points to my localhost).. I think its importing setting from my local machine not from the web server.. wierd!

notes: am using wordpress 3.4.2 and suffusion theme

pleas help me in this issue am stuck!
