The romps are fairly normal when she's cold, but a synthetic 5W-40 will do wonders for the startup. If it still romps badly at that temp (that's not that cold) after the oil change, you might want to have the glow plugs checked. The shift strategy when cold is to skip 2nd to make the engine warm up faster, so that is why it seems hesitant to shift when cold, when warmed up it skips 4th I believe for fuel economy.
