I definitely agree with Hal about using those cheap, low-quality no-name jacks.
I have seen countless installations where those were used and in a month the surface mount boxes or faceplates have the jacks falling out of them.
They are $1.80 each for a reason.
As for daisy chaining the wiring, it is a way to cut cost on wiring, but it is a PITA to troubleshoot. Try going into a house to do a repair that was daisy chained to find almost every jack covered by furniture, and you have to find the one that is giving the problem that is stopping the whole house's phones from working.
You will be moving furniture while I am in the basement disconnecting one pair at a time until I get dial-tone. By the time you broke that expensive marble table I have already found and fixed the problem.
It offers little flexibility for future expansion.
As for using the 8-pos jacks for voice that is also doing damage to the pins as Hal pointed out earlier.
If you have to shave the couple of bucks off your bid to get the work then so be it just know that there is a better way.
