ITunes not showing devices, how do I transfer an app that I purchased to my phone?

Question

I just downloaded the 64bit iTunes for Windows 7.  And I've just purchased an app that I want to run on my android phone.  The tab "Devices" is not showing up and is missing and therefore iTunes does not recognize the phone.  How do I get the app from iTunes to my phone?  Also, how would I get any music to my phone if the its not recognized.

I am having a similar problem. laptop crashed and we needed a new harddrive. Reinstalled itunes, downloaded "purchased apps" in itunes, then found I needed to "transfer purchases" and have done so and then backed up ipad in itunes. 
However, I still have apps that I purchased that wouldn't download in ipad and said would be available on computer in itunes.  I see them there, but all app boxes are greyed out and I cannot select those boxes.  If I somehow got it un-greyed, where I could check those boxes and uncheck the others, it wouldn't just add those, right - it'd delete the others?
Also, if I hit "sync apps" then it says it will erase ipad and apply the library, so I'll lose all info in apps.  In theory, I could (I'm guessing - tell me if I'm wrong and can't do this) tell it to go to the "back up" and sync, right?  But, It literally took 24 hours to "back up ipad", and I dont' want to have another whole day to restore to back up.  And, oh yeah, those apps aren't on the back up copy, so I'd not get anywhere but frustrated.
How can I get these apps on without losing my data?
