Hi Zack!
Welcome to Playmofriends.

Do you know about Playmodb? It is an amazing database created and maintained by a PF regular, Heather, who goes by the username of "sbblabotw". It has a lot of info about sets and parts as well as a search function. For example, I went to the site and searched for "grill" and found your second item very quickly:
30 02 6420 - Barbecue grill.
The first item took a little more detective work, but here it is:
30 60 7980 - Door handle - the piece you have is one part of a two-piece door handle set.
I was sure I recognized it, but I haven't put together a Victorian house in a while, so . . . .
Check out Playmodb - I'm sure you'll find it useful as well as pleasurable - lots of rabbit holes to get lost in.
