If I'd had problems with the tomatoes I would put them in the brown bin for collection - if not, they go in the compost bin. I don't grow cucumbers but the same would apply.
What is the barrel of water for? If you want it as a water feature the water will keep the wood moist therefore it will stay in one piece because the slats expand and are contained by the metal band. If they dry out it falls apart. If you want it as a planter it might be wise to line it - but you'll then need holes in the bottom of course!
Can't advise on the greenhouse or the Strelitzia, although I went to look at a house a few years ago and the vendor had grown one from seed. It was beautiful. He kept it in his conservatory - I expect he'd grown it in there - and was his pride and joy.
