Does a big shift sound strange?

Yes. One to four semitones sounds most natural; past seven the result picks up an obvious electronic edge, which is great for voice effects but not for a serious transposition.

Can I change speed without changing pitch?

Yes — use the Volume & Speed tool, where speed changes also preserve pitch.
