140G Upgrade

[BCWolfen]

So, I'm picking up Zerandise's 140G in the next week or so to U/G from my 90. I want to go more towards FOWLR but plan to keep my crabs and snails and avoid fish that eat them. I will also have some softies but do not plan on having any SPS. I currently have a 2" sandbed and really like the look of it. I also have 2 tigertail Cukes, 1 green and 1 brown bristle star. Everything I've been reading seems to be turning towards BB tanks. While I do not mind the look of BB I know for sure I would have to find homes for the Cukes. Would I have to find homes for the B'Stars as well?

I plan on cooking my rock and would be cleaning all the sand before transfering it to the new tank. Is BB really that much better or can I keep my sand?
