Help set up my first reef tank

Hi all,
I am new to this forum and i am here as i am going to be setting up a reef tank by the end of June(i like to plan early to avoid mistakes). I have been keeping freshwater fishes for 2 years and was at a lfs when i saw a beautiful reef tank and really wanted one. My new reef tank will be a 30 1/4 x 12 1/2 x 18 3/4 (inches) 29 gallon tank as i think that is a good starter tank size(but mainly because that is the largest tank i can fit in my house). As i am new to saltwater tanks,i decided to come here and ask you guys,the saltwater tank experts, some questions on how to set up my new reef tank.

Part 1:Tank stocking
1)How much live sand and live rock?
2)Fish stocking
3)Coral stocking
4)Clean up crew

Part 2:Equipments
1)Lightings
2)Filtration
3)Do i need reactors(calcium reactors,media reactor,kalwasser reactors,etc)
4)Do i need skimmer?If yes,which brand do you guys recommend?
5)How many power heads?
6)Can i not use heater because where i live the temperature(29 degree celsius) is the same all year round?

Part 3:Others
1)Food
2)Water additives

That is all i have for now.Sorry for the questions and thank you for reading my post.Thanks in advance.
