Pick a brick addict

Random pieces and a key chain I would like on pick a brick...

This entry may be strange but I've wanted some pieces that are new to me from pick a brick and on clearance from the Lego website.

The first 3 technic pieces are new to me...(see comment seeking input at the end of this entry).
The remaining pieces are printed tiles which I collect.

I like the silver Keychain above.  I was going to add this to the pick a brick order...siver chrome pieces seem so rare to me.

I don't have either of the above pieces but the top piece would hold rod pieces in place.i.e. guns on a fighter jet or a pipeline.  It would also be good for greebling!  

I wanted the cup above because it just cracks me up...Lego thinks of everything!  Even minifigs like coffee :)

 The first piece in the pic above is a new piece I don't have many of.  It could be great for converting horizontal to vertical as done in some car sets esp. the Speed Champions line.  On the bottom of the above picture is another flat tile piece I don't have. 

The first 3 technic pieces in the first (top of blog) picture are new to me.  I would love to know what sets they are in and their function. Please post a comment if anyone has input!  I don't do much technic building.  Thanks.
