Looks like a good plan, and the right way to go about things. Once you've got a few done, you might want to consider going up to 1/48th scale, given you have the space, as you may find things a little easier to handle, paint etc.
Of course, the bigger the scale, the more detail one is tempted to add, but that's for the future. Don't fall into the trap of wanting to try such things as scratch-building this, detailing that, weathering and so on - get the basics right, or at least to your satisfaction first. In other words, don't try to run before you can walk.
Have a look at some of the other modelling threads, in the 'Start to finish' and 'Group Builds', and see and learn how modellers prepare the kit parts - sanding off seams and ejection pin marks, ensuring the burrs from the sprue attachment points are smoothed away etc etc.
It's all the little things which make the difference between a good model, and a collection of parts thrown together, even straight out of the box with no additions, and, above all, never be afraid to ask a question, how ever dumb it might seem to you.
