It depends on what you plan to do with it.
Obviously, if you plan to work in a certain Arab country, knowing that dialect will be most useful. For example, you may be going to Iraq for military purposes, so it would be good to know Iraqi Arabic, etc.
If you want to be able to watch television and movies, Egyptian is probably the best dialect to learn since most Arabic language television (except for news stations) is made in Egypt. However, the drawback to learning Egyptian is that it is rather different from other dialects, resulting in Non-Egyptians understanding you (because of these TV shows), but you not understanding Non-Egyptians.
If you want to learn other dialects more easily, Levantine dialects (Palestinian, Jordanian, Lebanese, Syrian) are probably the most useful since they are more linguistically similar to other dialects.
The Najdi dialect of the Arabic language is most often heard in the deserts and oasis areas of Saudi Arabia. It is mainly spoken by the Bedouin peoples.
Whether you should learn standard Arabic or a dialect depends entirely on why you are learning the language in the first place. Generally, if you want to talk to people in informal settings, a dialect is better to learn. If you want to read, write, and conduct official business, learning MSA (also called Fus-ha) is better. Egyptian Arabic and various Levantine Arabic dialects are relatively close, like say Spanish and Catalan. While most Levantine Arabs will understand Egyptian Arabic, since Egypt dominates the Arab-language media, most Egyptians will not understand Levantine Arabic at 100% clarity.

Arabic -- although each country speaks a different dialect.
"Arabic" usually refers to the Modern Standard Arabic dialect, but the actual spoken dialectal Arabic used by regular people varies almost as much as different European languages. Egyptian Arabic is the most popular dialect because of their television industry and popular culture. One common difference from other dialects, is that Egyptian uses a hard "G" like in "great", while most others use a soft one, like in "age". "Eastern Arabic" most likely refers to the dialects used on the Arabian peninsula, and could be Gulf Arabic, Iraqi Arabic and/or Levantine Arabic.
Eastern Arabic is also referred to as Syrian Arabic. This dialect is most usefull in countries like Syria, Lebanon, Jordon, and Palestine. Other regions like Saudi Arabia, Iraq, etc., use different dialect, but can usually understand both Syrian and Egyptian dialects as well.
