hi,
If your domain and hosting is good. I mean if you already able to upload the files at your domain then you are almost 50% ready.
to install wordpress you can follow the following,
1. Upload all the files under public_html/
2. hit your domain
3. you will see the install process come to your front.
4. click next and then you will ask for database information. please create the database from your hosting and give DB name, DB user and pass and prefix
5. that's it you are done and you will see all the info in front of you.
If you are still seeing this problem. just post here, I will try to come with more solution.
Thanks
Mahmud
