You say you are new to photography, but how new? I've been doing it for about 4 years and still consider myself new. If you are not too familiar with using the SB700 then I suggest using TTYL and tilt the flash to bounce off the ceiling. Also, if you are shooting the blowing out of candles on a cake, definitely use the incandescent gel. It will help keep the glow from the candles without the cameras white balance turning it to white light.
