I have used Sibelius before. It was a very long time ago so I'm not sure which features have been added.
From what I recall this is basically musical notation software and nothing more. While that may not seem like much it is VERY good at what it does. You certainly get a "Professional" feel while using it compared to many freeware or low cost musical notation programs.
Keep in mind though, this is my personal "feeling" while using it. I'm certain that someone would disagree and say that Sonar is just fine. As far as midi keyboard Sibelius is simply a program that receives midi notes and little more. So it should work fine with any midi keyboard, no special hardware required. An excellent midi sound set on your computer would obviously help a great deal. How have you been composing in the past? I get the impression you have not been using a midi keyboard?
If there is a demo available I would recommend you download it and give it a try.
Oh and I almost forgot, it prints full scores beautifully, so for your purposes it may be worthwhile.

EDIT: If you are interested in becoming a "professional" then the money is an investment in your career and worth every penny. However, if you are just looking for a better tool for a hobby. Yes, look elsewhere.
