decent computer, controller keyboard, sequencer of choice and some plug-ins.
learn how the process works and see how you get on. if you're enjoying it and you're serious then you can start thinking about a desk, some outboard and hardware synths.. I would really advise anybody against making a massive investment in hardware without getting to grips with the basics first.
I've never been a massive fan of reason but I have to admit it's great for teaching people the principles behind sequencing. maybe have a bash with that and see how you feel?
rather than going for ones of those SAE courses off the bat try and hook up with somebody who already makes tracks. you can learn a shed load sitting with somebody who can take you round cubase or ableton; run through how to program automation where to find stuff or how to work with audio etc
there's also a bucket load of tutorials out there on the web. I taught myself how to use follow actions for sound design in ableton a few weekends ago using a really well thought out youtube tutorial. all free - abletons own forum is a mine of information and there are forums all over the web covering every piece of software you can think of.
as for ableton or whoever claiming they're all you need to start producing music. well that is true - ableton has it's own instruments, sampler, drum machine and native fx. it's literally a studio in a box...don't fall into the trap of thinking it's the equipment that makes the music. I'm constantly astounded when I read up on artists I adore to find they make amazing music with little or no equipment.
as for physical synths being a thing of the past. well I don't think so...but it's a pretty keenly debated topic.
over time plug-ins have started to sound better and better but even with a controller keyboard it's much harder to interact with them and sort of 'play them' the same way you would a synth.
I've come to terms with having to sell my hardware and convinced myself the plugs I use are pretty spot on but having worked with my friend dave gecko (of chems forum fame)again recently I spent about 20 mins playing on his Jupiter and it reminded me that they do sound truly amazing. much more 'alive' than any VST (and much more prone to going out of tune if you play with the octave cat)
that said plug-ins can do things which many analogue synths could never do. they're becoming incredibly flexible, modulation routing is a synch, preset recall?...no problem - how about morphing between two sounds you made three weeks ago?...and of course with a VST plug in you can program incredible detail into automation. something only an octopus could achieve with an old analogue synth..
anyway. I've probably sent a few people to sleep.
hope that helps.
