A:AnswerYes, all your streaming devices can use the same Hulu account. But, you can only watch Hulu on 2 screens AT THE SAME TIME unless you subscribe to Hulu Live and the Unlimited Screens add-on for Hulu. I have the basic ad supported Hulu and have 4 devices on the same account, just can only watch on 2 of them at the same time. I can watch Hulu on the Roku stick in the bedroom while my wife and daughter watch Hulu on the Roku in the family room.
A:AnswerYou can download apps to the Roku device itself, no special tv needed. It just plugs into any HDMI port and will show on that input for the tv. It is very easy to install, just a few steps.
