60A should be plenty for your garage I would think.  I'Go with a 12 space for the garage if you're worried about breaker space.  Don't need a main, but would be ideal safety purposes.

Pack of one $76, pack of two $338.  That's a great deal haha.

Will need 4 conductor wire from main panel to any 220v sub panels, sub panels need to have separate floating neutral and ground bar. You can use a main panel but likely wasting money on the unnecessary main breaker.

Eaton or Square D Homeline is fine, no need to get expensive stuff. If existing panel is something different, there is no need to match other panels to the main.

If Lowe's/Home Depot/Amazon don't have what you need, don't be afraid of the electrical shops.

Also, I'd defer to JJ but I'm certainly willing to lend a hand.

So you'll need a 100A/2P and 60A/2P circuit breaker that fit into your existing 150A panel.

100A feeder 3-#2, 1-#8EG Copper or 3-#1/0, 1-#6EG Aluminum

60A feeder copper: 3-#6, 1-#10EG CU or 3-#4, 1-#8EG AL

Residential wire is weird where it sometimes counts the ground and sometimes not, so be careful if you order.  I assume you'll use Quadriplex URD wire, Direct buried.  I don't do much residential, JJ or Mark can chime in on that.

power goes street to meter then splits to house panel (some sketchy 60amp main?) and back outside up the house to 2 poles over head to barn then along the side of the barn to its own 150 amp panel (newish and good) that only has 2 or 3 breakers in it though

this was the part i didnt get- what are pass through or feed through lugs?  relevant in this case?  do you need the 100 and 60 amp breakers, or not?, if so, put them in the panel, or put them at their sub panels as mains?

only reason i ask is getting to the 150amp panel is a long walk around the building and least convenient.   

if it was easy, id rather that panel just moved inside upstairs, but that needs national grid involvement bah.

Yes, you'll need breakers to feed the new panels.  The smaller wire must be protected.

Feed-thru or sub-feed lugs can be used to feed another panel of the same amperage.  Such as you could feed another 150A panel from you current 150A panel with no breaker.

Wha?

So the 150A is not fed from house?  It splits two ways after the meter?

Why not feed each sub panel with it's own breaker in the main panel?

I understand the reasons not to (since there's no upstream breaker to disconnect) but how much more sense could it make to swing the existing 150a barn panel upstairs and just do one sub or perhaps just run 2-4 circuits to the garage?

to much hassle to have it shut off at meter to move pannel.  also I want the shop sub panel to be closer to the shop area which is 30' feet further away.


two subs off the 150 in the shop and evaluate the house panel is the way to go.
