Here are some tips:
If you are new to emule, the official site is the place to go:
http://www.emule-project.net . All questions you have should be easily answerd in the faq's and the help file. Tougher questions should be asked in the emule forums after searching first.
I would recommend the regular emule version found on the home page for now.
Best thing about emule is the availability of files. It can be very slow, but that is usually based on the number of files you are downloading and the number of sources for each file.
A file with low sources could take weeks or months to finish. A file with incomplete sources (parts in red) may never finish, but it never hurts to ask on an appropriate forum for a reshare.
Welcome to emule.
