i would advise you against spending any real money on software at your level. you want to learn, and see whether producing is something you like, and have any talent for. no point in spending any serious money on something you may not like.
id say get Reaper. you wont have to pay anything to begin with. just download the program from their website, and if you like it, you can decide to pay them their very reasonable fee. As far as using reaper, its pretty much the same as most major sequencers, both in functionality and sound quality. and in my opinion, it would be better for you to get used of working that way, rather than something like reason and ableton.
Similarly, there's tons of free and/or very cheap synths, samplers, and effects that you should try out, before splashing out any money. KVR is the best place to check for all VST needs.

now, if you are sitting on some hot cash that you simply must spend, id say your priorities are as follows:
decent computer (anything with a 2.4 quad core and 2 gig ram is more than enough for now)
Soundcard (again, no need to go crazy. edirol's UA-25 is very solid, and for even cheaper you could get M audio's delta 44)
Monitor speakers (example, Alesis M1 MkII, or even cheaper ones)
Midi controller (just a simple 2 octaves with a few knobs, eg M audio Oxygen)
Large computer screen (22" are dirt cheap right now)
so yeah, thats in my opinion your best course of action for equipment. in terms of knowledge, just keep checking places like dogsonacid, gearslutz, and of course our production forum here. some great heads, like kama, dar kist, logikz and many others, with tons of knowledge.
good luck
