I've been doing a lot of research on this recently, and some buying and testing in preparation for some self-sufficient any time of year touring with wild camping thrown in for good measure, and firstly, I'd say that I admire you for trying it, and encourage you to try again.
A little suffering is good for the soul, and great to look back on and laugh.
I have to say, I prefer Trangia type stoves.
I have a great little cookset and stove. It's a Clas Ohlson Trangia copy, but better designed:

It's smaller and lighter than a the Trangia 25 and 27, and boils water faster (albeit by only a minute or so). I have one and my traveling parter, so we can both cook at the same time and not rely on cooking everything in one pan (which is slower).
Thermarest type mats - you can get a great copy from
Decathlon. Cheaper, only a bit bigger and heavier. Really worth it if you're on a budget (or just don't want to pay stupid prices):

It's three season rather than four (but so is the normal Thermarest pro), and you can put bubble wrap under it, or sections cut from an old fashioned foam mat, to boos it to a four season.
Sleeping bags. You can get a cheap down bag from Tesco:

It's no good on its own for anything other than spring to autumn (and that's just me. I find anything lower than about 8 deg, and I feel the cold), but put inside another bag (so long as it's not too tight a squeeze), and it works really well to make things very toasty indeed. If you also use a silk liner and a pertex cover (both about £15), you have a very adaptable system which. I've used liner, down bag, 3 season bag and pertex sleeping bag cover down below zero, and been happy. The whole lot weighs about 2.5 KG, which is heavier than a single bag, but it's flexible. I can use as many layers as I want, and I can pack it separately. Also, should my down bag get wet (a constant worry for down bag owners), I've got a back up.
Down jacket. Just got a cheap one from Decathlon in the sale (£26) - no too big, but really useful. You can sleep in it if it gets that cold, drape it over you, keep yourself warm after cycling, and,best of all, when not wearing it, put it in a stuffsack and use it as a pillow. Mine weighs about 600g and packs down to about the size of a flattened toiletroll. It's lighter, more compactable and warmer than a fleece. great stuff.
That's about it for now.
