I think you`re screwed with the brooch, unless you plan on searching the whole docks district again, which obviously you aren`t. There`s also a fountain or something that is supposed to respawn key items, but i don`t think that will help either.

For Grimgnaw you need to be in the blacklake district in a house in the northwest section of the district, you`ll find a ring.
For Tommi you need documents that are in Thomas Wheelwright's Wagon Repair in the southeast section of Beggar's Nest.

Btw i think you`re not really supposed to gather all these items, i think the point of the game was to take one henchman along and get his item. But of course you`re free to get these items, they can be really good (depending on your class) and it`s not forbidden to become powerful. I never took a henchman along, so i just spoke to them for items (in my second game that is, at first i didn`t know they gave me items).

Just finished chapter 1 with having completed Linu's and that Half-Orc (forgot his name).

Ill call him Ug-Ug for now.

lol. his name is daelan.

what you playing as? first time through?
