When your gallerist, or you, decide to make an exposition, it is a series of works, or just all kinds of works from your life?
How do you fill the space? Do they give you the entire gallery? Do some not allow certain audio, or video works?
I think Rekulas Answer is great.
The first thing to do is research the Galleries you think might be interested in your work. Look to see what kind of presentations, exhibitions and type of work they focus on. Get a gallery guide from each one with a list of current and upcoming exhibitions. Most galleries plan these many months or years ahead of time.
If you are interested in just having a gallery show some of your work, the same homework applies. The more research you do on the gallery and their wants and needs, the better off you will be to create a body of work and display type that will suit the situation and your form of art.
You should ask for the "gallery submission" guide, and see what they list as general requirements, and then if you feel you have a fit, make contact to see if there are any openings or if you can schedule an appointment with someone to discuss the possibility.
But before you even approach the gallery, you should have a solid working knowledge, and preferably first hand look at the gallery you are interested in approaching.
As for the body of work, most galleries like to see some continuity in the work, such as one or two series and definetly not a jumbled mix of different styles or from different periods of your life. (that is unless you are famous and they are doing a retrospective 
)
Galleries want to show your best work, and it should have a consistent theme or style and quality to it.
As to whether you take up the entire gallery or not, that is up to the space and needs of the gallery, and not usually for you to decide. This you will sort out in the conversation with the gallery director when you reach this point of being asked or accepted.
Good luck, and I hope this answers some of your questions.

it depends. are you talking about a commercial gallery? if so, they are interested in sales and display power. first I’m going to answer as if you are talking about a commercial gallery. for a new artist, they want a body of work that shows a "direction" and craft. it doesn’t have to be a series, but it helps. for an established artist, they want new work (completed withing the past two years), not stuff that has been sitting around the house. a commercial gallery will select the work they want to display, and set it up for you. they may do a one or two man show featuring your work, if they think it is very marketable.
museum’s and non-profit galleries are more lenient and liberal. they are where you will often see the off-the-wall and cutting-edge art, including audio and video. a non-profit or co-op gallery is where you will often see "installation art" and emerging young artists.
