Brand NEW Mac user! Do i turn off my iMac/keyboard/mouse when not in use?

Asked by futurelaker88 (1600) February 22nd, 2010 from iPhone

i just made the (i can’t really say “switch”) from pc to Mac. I still have my PC. but I just purchased the new 27” iMac with the magic mouse and wireless keyboard. I’m BRAND new to mac and really have no real grasp on how it works from an experienced perspective. I am really versed on windows and can do more than most, so I feel out of place on a Mac. I use them in school all the time, but never had to deal with troubleshooting (downloading files, codec issues with video types, knowing what programs work with mac; or applications I guess they call them, etc.) for starters is it normal to turn off the magic mouse when I’m done using the machine? or is it meant to be left on and will “sleep?” same question with the keyboard. another question i guess is….for windows i just search and download (software), it seems on a Mac I have to go to certain, specific websites to get specail “applications” that are compatible. is there one place to find all these apps? like an app store? or do I just search for what I’m looking for and hope an app is available? lol these seem like childish questions but I turned on thr iMac and stared at it realizing that i don’t know what to do with it!! until I can afford “Final Cut Pro” which was the real reason I purchased it to begin with. thanks guys!!
