Nick,

   I'll confirm it for you.  You need to position your chip 90 degree clockwise from how you have it shown.  I confirmed this by examining an SX48 protoboard in addition to the document you referenced.  When positioned with the text upright (as you have it shown) the oscillator pins will be found at the bottom edge of the chip.  But the text is not what you should use as a reference.  Use the dot for proper alignment rather than the text.  The dot is your friend!  It should be positioned in the upper left hand corner for the board orientation you have shown.

   Also, it is good practice to connect ALL of the power pins.  Multiple pins are provided for good electrical performance which includes allowing for the rated amount of current to flow through those tiny pins.  It is possible that your circuit will work just fine without all of them being connected.   Just keep in mind that whenever possible it is a good idea to connect them.
