poker chips are so cheap now id always reccomend paying that tiny bit extra and getting a 500 chip set instead of 300.
i think having the value on chips helps with newbies and guys you havent played with before. If your playing with the same guys every week its never gonna be an issue. I got a 500 chip set over a year ago and all of the lower valued chips have lost the gold writing which states their value. However, everyone knows that the black chips are 100 etc
with regards to having 500 or 1000 chips. Its irrelevant. You just need to set chip count and the blinds according to what you set each chip
if you have any questions though just ask
