For C*-algebras we usually don't assume they are unital; this is the whole point of concepts like approximate unity. 3. The ring of bounded continuous functions on Y is isomorphic (as C*-algebra) to C(X) where X is the Stone-Cech compactification of Tychonoff coreflection of Y. Just assume compactness. 4. This is not a generalization, it's a different but related concept..)
