Hi Alex,
I was in the same place - minus buying a DSLR. I'm 20 now and started shooting when I was 19.
Let me know if you have any questions - if you can, get the book "black and white photography"... Even if you choose to end up using colour, black and white film will challenge you as an artist - You must present the item in question relying only on shades of grey. That is, it challenges your composition, and not only that, but challenges you as an artist - without relying on "pretty colours".
In any case, black and white is also good because it is cheaper than colour, and second of all, it is very easy to develop yourself, when you feel ready. Here where I am, in the USA, developing a roll of B/W is $8 a roll. I save over $70 processing 10 rolls myself... In fact, $25 allows me to develop somewhere around 30 rolls of B/W myself... Compare 8*30 with 25/30 ... The savings speak for themselves, and I have full creative control.
But *all* in due time. Focus on the images, and learning your TOOL... The TOOL that presents your own inner art to the outside world. Master the camera first, and then worry about developing - or at least have a very solid grip on the basics.
