Sounds like you are loving riding and there is nothing better than getting your first deck. Yeeeaaaah!
I'm 1,80m but very light (60kg) so i think i'll go for an 154-156 or sth.
Most board buying mistakes are made right there. No rider has a specific board size and a range of 2 cm will overly limit your search. While there are some boards in that range that will be great for you, many others will not (and you will miss some great options as well. You are roughly 130 lbs. We will also need your foot size to make some strong suggestions. Rider height is not a factor in board sizing. It sounds like you dig Rome products. Great brand. Any other brands that you have your eyes on?
