Firefox,
The Tamiya CVA Super Mini Shocks #50746 are the ones to get. The others are to long and you will not be able to drop the car enough and still have any droop.
The best alternate is to get the Tamiya M Chassis TRF shocks or if you have normal TRF shocks add a 4mm spacer underneath the piston.
For springs if you get the Tamiya CVA super mini shocks then get the short TRF mini spring set PNo 84117 or the TC Short Spring Set PNo 42168.
I think you should have a good read of the rc mini net site, which will be able to answer the majority of your mini questions.
Another alternate is to get the 3Racing shocks, come in a packet of four and come in different lengths.
I refer to that site regularly and point others to it often.

Calvin.
