This is not possible, the original (classic) World of Warcraft must be installed first as the Burning Crusade is an expansion (addon). You can download the installers from the World of Warcraft website.
download the addon. Should be on a zip file. Simply extract the file. place the folder with all the files in your >world of warcraft>interface>addons folder.
A must have addon for all raiders in World of Warcraft is Deadly Boss Mods, also known as DBM. This addon will cause warnings to pop up on your screen when important things are going to happen. An example of this would be on the first boss in Heroic SFK. DBM will tell you to interrupt his self heals and will also warn you about when he about to transform towards the end of the fight.
Here is the normal installation path for the interface/addon folder: C:\Program Files\World of Warcraft\Interface\Addon
Download the addon. You can usually find this on the Curse Addons website (listed in the links). Save it. Then move it to your addon folder in your World of Warcraft folder. To find the folder go to your wow folder, then interface, and inside that should be addons. Next time you are at the character screen an addon button will be on the lower left.
In order to manually install an addon, first download the addon and unpack its zip file. Everything contained inside the zip file should then be copied into the World of Warcraft\Interface\Addons folder. When you start up World of Warcraft again, click the "addons" button at the bottom left of the character selection screen and make sure that the addon is there and the box in front of it is checked. The addon should now be running properly. If the addon has not been updated for some time, you may need to click the "load out of date addons" option for it to work, but this increases the chance of the addon causing errors.
You don't unlock the XP/reputation bar. It can not be moved unless you use an addon to move/resize it for you.

No. But you do need 3 for frozen throne (addon) to work.
No, addons do not cost money. As a matter of fact, Blizzard recently changed their Terms of use and Acceptable Use Policy to require that addon makers NOT charge for their addons, although they can ask for donations on the addon maker's website.
