Weddingbee boards

Hey everyone, my FSIL wants to have a honey-do shower for us. I need some advice on the following...

What would be a interesting and nice hostess gift for her and her husband (he will be helping cook etc).

Our wedding is less than 30-days away and some people have sent us gifts already and i dont want anyone to feel like they need to send us another gift becuase we are having a shower, we just want to enjoy their company and have a relaxed get together.

Also are we supposed to invite grandmothers etc to this shower? My grandmother lives out of town and we would love to have her but dont want her to feel she is obligated to send a gift.
