I do not use any silicone or cement on the appliance adaptor. Silicon would just melt and cement is unnecessary. Just snug them up and screw/rivet them in. I used silicon under the top plate to keep rain out. I also use a full cover cap to completely cover my clay liner.
The single wall liner is good. Not sure about your particular brand but mine (Olympia) was real nice. I installed a Easy Flex and a Heavy Flex in the last two weeks and the Easy Flex was much easier to install but if you don't mind the extra work and if you value extreme durability then the Heavy Flex is what I'd recommend.
