XT1 & 56 1.2: what next (light and sharp) ?

Waiting my new XT1 i've bought (as first lens) the stellar_sharp 56 1.2.

I love to take portrait (also when travelling) and looking for the sharpest lens available.

Now just wonder: what could be my next lens ?

35 1.4

and 16 1.4 when it'll be delivery this year

or

23 1.4 (newer and with better autofocus than 35 1.4)

or

10-24 4

16-55 2.8 (seems too bulky and heavy)

Probably 3 primes would be the best choice to stay light and have sharpest/better IQ, though changing lens has its own disadvantage over a zoom ...

Btw the Fuji lens come with a pouch ?
