Only came to this thread but I may start a thread at some point about if I had to do the whole thing over again.
You've made the right start, I'd also buy a can kit with all equipment for brewing.
I'd jump straight into all grain after this, following
Clibit's guide. I wish I'd done this sooner. The only extras needed will be a thermometer and a muslin bag.
Next step would be a fridge, essential if you want to brew lagers and not a big expense if you pick one up on Freecycle or Gumtree. Space is the only issue but that gives you an excuse for a man cave :)
Followed by a boiler and chiller (buy the false bottom for the boiler), it makes a big difference.
Finally I'd consider Mini Kegs and Corny kegs.
I've done some of those steps the other way around but if I done it in that order I'd have saved myself a lot of time.
It also sounds expensive and it can be but if you take things slowly it doesn't have to be that way. Add little bits at a time and buy things like your thermometer from China <ã2 but delivery can take 6 weeks)
A Can kit can cost ã10 upwards for 40 pints while a simple SMASH lager can cost as little as ã7 for the grains, hops and yeast and will taste so much fresher and better.
That's a quick summary of how I'd do it but the kits are a great place to start. If you've no bottles use 2L fizzy drink bottles. They can be a pain to use but they're cheap and disposable.
It's not rocket science but I'm sure you've many questions and this forum is a great resource. We all started somewhere.
