I'm looking to get my Commercial certificate once I finish my
Instrument rating and am trying to meet as much as the requirements as
possible. I noticed it says in 61.129:

....
(3) 20 hours of training...includes at least---
....
(iii) One cross country flight of at least 2 hours, VFR, 100nm...
(iv) Same thing but night

Now for my private training, the requirement was 100nm for the
dual/training flight (and a 150nm solo flight).

Since we were flying a slow plane, and it took 2 hours, would this dual
cross country fulfill the commercial requirement?

Also, for the 10 hours of dual complex time, can I do this anytime?
(I'd like to use a 150 that I have access to cheaply for most my
commercial training, then do a few hours of complex just before the
checkride to be ready).
