I assume you live in Australia?
I have a Kelty Noahs Tarp that I really like. There are probably better options but I got this at discount, and have been really impressed with it.
I also have some REI adjustable poles - Kelty also makes something similar.
I actually have that same GSI table. It is a pretty nice little piece of kit, although it takes some time to slide the two crossbars through the slats. It gets used for cooking, side table in the tent and next to my low height camp chair. Although most would consider it a luxury item, I find I get an awful lot of use out of having it.
I looked at the other tables, and I really like the Helinox one, but right now I don't think I will be getting it as this little GSI does fine.
Those canister stoves will burn for a while on a single can. I think Australia has more of the butane cans available compared to the smaller iso-butane canisters like Jetboil, etc. use. I could be wrong though. I have a mutifuel myself that runs off white gas, kerosene or regular unleaded. Works well, but it is heavier and more complicated to use. If all I am doing is boiling water I use my alcohol stove instead. IF I am going to do some actual cooking that involves simmering, etc. then I will bring one of the other stoves.
I have a 9' Kelty Noah's Trap and I love it. Here is my set up https://www.flickr.com/photos/55068188@N06/17344464715/in/album-72157649983862834/ if you wanna buy it http://www.amazon.com/Kelty-4082021309-P-Noahs-Tarp-Shelter/dp/B00AA6SX8A
Polyurethane coated nylon is one of the most common materials for tents and camping tarps. If you can't find a source you could use a tarp for material, like this one: http://www.amazon.com/Kelty-4082021309-P-Noahs-Tarp-Shelter/dp/B00AA6SX8A
