It appears you are looking for one unit to serve all purposes. If this is the case, you are looking for home-theatre-in-a-box systems (HTIB). There are a number of options out there. It depends on your budget and other factors like size of room, etc. I personally think you would be better off buying an receiver, bluray, and speakers separately. It will cost a little more but you will have more options for the future. For example, the bluay fails in your HTIB system, guess what, you need a bluray. Also, HTIB solutions usually have a very limited number of inputs. So you may not be able to plug in that new bluray player. There are many 5.1 speaker options for very cheap for receivers. Many bluray players can be had for around $100. Decent 5.1 small speaker set ups can be had as well.
