Mobile device policy enforcement with Exchange Active Sync [v2.5] and install apps from the Windows Store, is it possible?

Writing this in a code block because the WYSIWYG editor does not 
want to work in my browser.

I have a fleet of 150 Windows RT 8.1 devices, I have a SBS 2003 
SP2 that I intend to implement Exchange Server on. The primary 
reason behind this is so I can take advantage of Exchange Active 
Sync's Calendar & Global Address List functionality.

My intention was to register each POP3/SMTP Account (hosted on 
a seperate provider) as a Microsoft Account, then use the Exchange 
Connector to download the messages and serve them up to my devices via EAS.

Questions: Will I be able to use these Microsoft Account registered 
'mail' accounts as the logins for the devices so I can download 
applications from the store? [requirement set by management above me]

Am I misunderstanding EAS in that it enables device management
 to an extent? ie. Can I use EAS to force a wipe, lock or password 
reset on the device account?

Apologies if my questions are simple or poorly structure, I've
 done extensive research but I hail from GNU/Linux land.

Thanks,
Dom
