Definitely go for a rooted plant. It can be a pain to root, especially if you are new to hoyas.

It toletated my West exposed window sill just fine, so it should have no issue tolerating an Eastern exposure. It tolerates more light exposure than people give it credit for; that being said, direct sun is a no-no.

This one also prefers being grown with a lot of moisture (semi-hydro works quite well). The downside to semi-hydro growing is cool/cold seasons. If where you live has cold or harsh winters, you will need a heat mat to prevent root rot. Cold, wet media on fragile, tropical roots is no bueno. It would also be wise to remove the plant from the window sill (if you are placing it there) and move it to a warm, draft-free area, for the cold season(s).
