The routine for back and chest (day1) says:

Close grip chins: 2 x 9 - 11

and later on it says

Wide grip pulldowns or deadlifts: 2 x 9-11

I'm doing CG Chins and then WG pullups, since I dont have a lat pulldown machine, and I don't want to do deadlifts (i have a reason - long story).

but the CG chins really tire my lats too much - and I really like doing the WG pullups because it puts more focus on the lats and less on the biceps.

Can I switch the order of these two around? ie

first WG pullups
then CG Chins.

will that be okay?

also, how close is "close grip"

should my hands be touching?
