If you are going to get Ampeg, either get all-tube or some other brand... you could spend your money better else where if it is SS or hybrid you want.
I agree fully. If you go Ampeg look for the head I use, SVT II, or an old school SVT, the new SVT-VR would be great but its expensive.
If you go SS because I recommend Gallien-Krueger...I would say 1001 or 2001 RB heads and get one used (it should be affordable)
Cab wise- I have heard Strung Out use Aguilar live and I think they are great for what you want. My preference is to what I own and use-MESA, but it's expensive. I think a 610 or 810 would be good for you if not a 412 (Mesa, Aguilar and GK make them) Ampeg is not a bad choice either. A 410 alone I don't think is enough you need to add a 15 like I did or maybe a 410 + 212...you need to push air man.
