doubts regarding fpga spartan3E kit use.

I am newbie in using FPGA and while using spartan3E starter kit I have tw
doubts.
1.I am making a simple ADC to DAC system using on board ADC and DA
chips.Do I have to provide 3.3 volt( for creating reference voltage) t
header J5 through external power supply, or does the board has its ou
circuitry to provide that internally(from its own power)?I think same wil
go for GND too.
2.I have to store samples coming from ADC ,store in memory and d
processing on them.what will be of better use, FIFO or RAM?and how muc
memory is available,because it seems I must obtain more than 1 Mega sample
per cycle for my purpose.
