First of all: Happy Birthday! I'm sure you're gonna have loads of fun cycling. And the best part: buying cool features is addicting as hell! It never ends; there's always something else we wanna buy. I loved that valp cap, hah.
I think you made a good choice by going for V-Brakes (easy and cheaper to maintain) and you can always upgrade when you get to the point of doing more hardcore stuff (where the discs will be required). Many travelers don't go for discs too.
