recording studios come wiht other instruments?

Well, seeing as I only have two guitars and a keyboard. If I wanted to like really record something, with like a drum, and other stuff, does the recording studio come with that? Like different drum tracks.

Forget that route man, either come with some midi drum track (EZdrummer or something similar) that you can get sounding good in the studio or have a drummer hire out the studio kit. Making up drum tracks takes a long time and you will blow most of the time trying to work out something that you would ultimately want to change... If you simply can't get the drums done and have no cash for software, download something free like hammerhead http://www.threechords.com/hammerhead/introduction.shtml and just use it as a scratch beat. Spend all the time gettingthe guitar, bass, keys and vox parts right - you can then take this with you and add beats later or when you get a drummer. If the track is not too complicated, post a link of a home recorded demo recorded to a metronome with the exact bpm and someone here might be able to throw together a drum track for you - basically forget going to the studio without everthing worked out unless you are a very advanced musician with a lot of experience in creating off the cuff.
