Just from what you've said - I can totally understand why you'd be feeling this way - I would be too.

She sounds like the kind of MIL that could be controlling and I can sense she may try to assert her 'baby raising habits' with YOUR bubba. I really hope she will at least respect your wishes and comply with your wishes, re - no walker, the smoke situation etc.

My mum has a cot set up for DD, a high chair etc but she only looks after DD when I need her to. It sounds llike your MIL is planning on having your bubs on a regular basis. The evidence being she is setting up an entire nursery for bubs.

Then again, with my MIL's (yes, I'm lucky enough to have two - a step and a natural ) they have their favourite hobbies / people for a month and then before you know it something else comes along and snaps their attention.

Maybe over the weeks / months to come try (your DH too) dropping subtle hints about what it'll be like when the baby comes along e.g. "oh, maybe you'll be able to have bubs overnight when we go out every now and then" (trust me, you'll appreciate that )...
