Personally I would concentrate on doing your 'vanilla' PPL first before you worry about cloud flying. You are not allowed into cloud (bearing in mind there are no 'stop' signs on the outside of them...) with a plain PPL anyway, you would need to do the instrument rating to get the bit of paper and more importantly the training that allows you to do it.
Flying in cloud can be very disorientating even with the proper training. Without the proper training it is often fatal. I have had the 'leans' once and that was enough, I was convinced I was doing a slow roll to the left. It took all of my concentration to stay right side up. It probably only lasted less than a minute but it felt like hours.
Good luck with the training, you will enjoy it but take one step at a time.
