You're using almost the exact same weights that I was, when I started. You should be fine with those, if you have a pair of relatively-good sized testicles and you eat as much meat as you allude.
Consider lacto-fermented oats, to eat with breakfast on the morning of training days. You will need those carbs once shit starts getting heavy, trust me.
Other wise, sally forth, and start with those weights if you want to.
