Good questions. First off sounds like you will need more stuff! Before you can start the engine you will need to have some way to get the the fuel from the bottle into the fuel tank in the plane. It can either be an electric pump or a hand crank pump. Now you need to provide power to the engine glow plug before it can be started. The best way to do this to have something called a power panel. It has an adjustable knob and a meter so you can see how much power is going into the glow plug. Next you need to be able to spin the motor over safely. I would suggest an electric starter for this. You can go cheap and use something called a chicken stick but new motors can be hard to get started without a starter. Since the fuel pump, power panel, starter, are all run off a 12 volt lead acid battery rated at least 7 amp hour. It also means you should get a field box. Mount the power panel on the outside and the battery inside. You can also carry your starter, spare props, tools, ect. in the field box. These items are considered the basic "stuff" you will need in order to even get the plane flying. You should get the items and then call your instructor. To go to the field without these basics will just result in zero flying time. The field box doesn't have to be expensive. You can buy a plastic tool box of a decent size that looks good. I bought mine for $10.00. I know you had other questions but your instructor can take over from here.
