Hi,
670 is decent score with 8+ years of work experience so I would surely encourage you to apply to ISB and XLRI. You can also consider applying to Greatlakes, SP Jain,and you can also consider IIM's.
Regarding recommendations I would suggest you to follow whatever b-school asks you if they mention they need 2 recommendations then you should submit 2 recommendations otherwise b-school will consider your application as incomplete.
I would suggest you to take recommendation from work place, as you were involved in client facing role even recommendation from client who knows you very well would do. I am not in favour of getting recommendation from acads, as you last visited your college 8 years back and many things have changed since then so how will your principal/teacher know what you are at present??
You can take recommendation from 2 different organizations it should be in sync with your application essays.
Let me know if you have any questions...you can also PM your details for discussion.

and btw ??
1) do we necessarily need 2 recommendations or only 1 would do ?
2) would one of it be necessarily from acads or both can be from work place ?
3) can I take 2 recos from 1 org only ? or both have to belong to different organization ?
