I would add to 3, Members' Ability to see their own offers in a summary list (with a clickable Request link to jump into them quickly and check the request or remove/edit the offer)
+ a column of 'offer experation' when the points committed will be returned if the item is not filled. this would not be editable but just for information so people can budget points and know when requests are going to expire.
Also, I would love the ability to bid on an item after it is filled if I want it quickly. In an idea world the person fufilling could say 'automaticly email the link if X points are bid'
Thanks for all the hard work everyone is doing on this, it is amazing and very very nice to see such effort.
