hi david,
welcome to the forum. I am sure you will find reefing a rewarding and enjoyable hobby for years to come if you can do things right by follwoing the advice of the bros here as well as lots of reading.
lets see about your questions:
1 feet tank: the size is ok, but of course bear in mind that the amount of livestock you can keep in pretty limited. No big fishes and just one or two nano fishes. also, check the tank thickness, 10mm is recommended but u can do with 8 i guess. saltwater has higher density than freshwater thus the tank might not support the weight if it is too thin.
ohf: ditch these, they are a yesteryear's product and not meant for marine. It is better to have a canister or even better, a sump.
lights: depending on what are u planning to keep. lighting for fish only tanks can just be basic but if u are looking to keep soft corals and lps etc, T5 minimum. for 1 ft size, it is hard to find T5 for your tank, 24w T5s are the smallest and they are meant for 2ft tank.
low temperature: some bros here use fans to keep water cool, but bear in mind the high evaporation rate. chillers are relatively affordable nowadays. why not invest in a chiller to keep your livestock happy? unless of course you are planning a fish only, then they can tolerate high temps compared to corals.
surface skimmer, protein etc: protein skimmer helps to skim out the organic waste in the water, it is a necessity unless u employ other methods of nutrient control, zeovit, macroalgae, scrubber etc. surface skimmer helps eliminate the unsightly film on your water surface, it is just an extension of your filtration system.
wave maker: water movement is paramount for a tank. imagine you in a room with no air circulation, it will be stuffy and uncomfortable.
bigger tank say 2 feet, for easier to control stability? of course a bigger tank will give you better control and ultimately, more space for corals! but it is all up to individual choice. for me, i regret my 2 footer cos i am running outta space for corals hahaha.
I do not intend to have any bottom sand: barebottom or sandy bottom are all up to individual choices. bear in mind that some fishes such as wrasses, needs sandy bottom though. so do your research about the things you wanna keep and try to create the best environment for them.
keep posting questions and do lotsa reading and you will get a very rewarding hobby for years to come!
cheers
