Best use of Hilton points?

I booked Hilton at Santa Barbara using Chase UR.
Because I got a room for 15k with chase whereas the same room cost me about 73k HH points.

I am not traveling for work anymore- should I get out of HH?

Where can I best use HH points? BTW do they have a mall to buy stuff?
Can I transfer HH to something else? Which one?
