Help with installation of Dolphin 6.1

I will install Dolphin software to 6.1 and I need some information to be sure -

The software is uploaded to http://www.myserver.com/home/user/public_html/

I need to set URL for Dolphin folder -

Do I need to set -
http://www.myserver.com/home/user/public_html/   or
is it http://www.myserver.com/public_html/ ?

Directory root: This should be the server absolute path to the Dolphin software.

Do I need to set -
http://www.mysever.com/home/user/public_html/   or
something else?

Path to php binary: Here you should indicate the absolute path to php executable file on your server
do we need to set - 

http://www.myserver.com/user/local/bin/php or

only  user/local/bin/php?

The detailed installation for Dolphin 6.1 tells -

'''SQL file''': this is the relative path to the database creation file, which is determined by default. If your file resides in a different directory, you should indicate its relative path here. The base folder of the path is considered to be the Dolphin installation folder.

I made a typically installation of a new database and I guess that the relative path for the SQLfile is – http://www.myserver.com/home/user/public_html.

'''NOTE: Do not forget to install [http://www.boonex.net/ray/wiki/RayServerInstall Ray Media Server (RMS)] if you're installing an Ad-Free package.

How is this media server installed? Will it be downloaded first to my computer and the uploaded to any special folder on the server?

Finally the detailed install doc tells to (Step 4) - run the install script -
Using your favorite web browser, navigate to install/index.php- I might be a novice, can the index.php be opened with the ftp program or how to navigate with the browser to that file and execute it with within the browser?
