In my early 20's while I was in 'old blighty' on the obligatory antipodean OE, I decided to tour India on my rigid fork MTB(no shocks in them days) I had next to zero wrenching skills but for some reason I never even considered what could go wrong. From memory I took a few spokes and a puncture repair kit for a 6 month tour of duty, somehow I survived with the odd puncture... Read up on basic maintenance, have a go at changing cables tyres etc before you leave, then get on that bike and ride
