Yeah, the head has ample power. No worries.
As for cabs, yep, it's always best for them to be identical. So in this scenario, a 410/410 or 115/115 is the best option. You decide which tone you prefer and/or how much potential loudness you want/need and/or how much money you want to spend, & double up on the cab that covers more of your bases more closely.
Lots of threads on mixing to check out. Bottom line is that identical boxes always
work together (a 410/115 from the same manufacturer & same series is still mixing). Non-identical boxes (this is a better way to describe it) are always a crapshoot
. You might like them. You might not. But even if you do
like them, the strong odds are that you'd like identical cabs better
. Possibly much better.
If someone must
mix cabinets, a 4 ohm
410 & 8 ohm
115 (again, from the same manufacturer & same series) is one of the better choices. The 410 (which is two 210s) would get twice the power of the 115. A 115 can be kinda thought of as a differently configured 210. It moves about the same amount of air as a 210, a bit more actually. So what you have, in essence, is a 610 stack, & each 210 is receiving the same watts.
One box being 8 ohms & another being 4 ohms can be, & almost always is
, a problem for solid state amps. The total load for a 4 ohm/8 ohm combination is 2.67 ohms. Very few solid state amps will support a 2 ohm load. And if they don't, they'll fry. But the VB
-2 does 8, 4, &
2. So no worries in this regard.
Good luck with whatever you choose.
