It's not too hard.

I recommend one of these:

And a temperature controlled iron (the $40 one from Circuit
Specialists is a bargain.)

It's not too hard to solder surface-mount stuff.  Use a paste or
liquid flux.  The surface tension of the solder can actually help pull
the chip into alignment with the pad.  With some experience, surface
mount goes faster than through-hole.  (you don't have to keep flipping
the board over!)

Keeping ICSP when you have other stuff connected is possible, but
sometimes tricky.  If you must use a 10F200, try to get one of the DIP
ones for prototyping your circuit.
