Okay, so I have tested out and refined my gear a couple of times, and This is what I ended up going with.

I, too, absolutely hate bugs, so bug protection was pretty necessary. Another thing I hadn't considered was actually room to sit up on the inside. Especially if you have extended stay in mind. For reference, I used to have This, but when I tested it, I realised I couldn't get changed inside it with any degree of comfort, or indeed do much at all.

Also, you haven't mentioned a sleeping mat. Do you have one? I've tried sleeping without one, in late early October (early spring for you guys) and not only was it really uncomfortable, but the ground just sapped away all my heat, even though I had a sleeping bag. This is pretty cheap and should help at least a litte.
