You managed to login, i guess you enter your password right, if you did something different please post what you did.
Now, Did it boot ok?, i mean did you saw any red text like this
NOw, about your last question,
but now it is saying something similar to:
That is the command prompt, you read it like this (<user>@<host>) the host is he name of your PC, when you installed Fedora you typed those numbers as the host or something, if have leaved it empty it will be named localhost insteaad of those numbers; but donīt worry you can name your computer whatever you want.
by the way, what are those numbers? did you typed your password where you should have tipped the host name?
You can change it, so donīt worry
