Yeah I agree with tamfb, you need access to a better facility for your training. It shouldn’t be that hard to find a relatively decent one nowadays.
As far as your body fat % is concerned I don’t think you have a lot since you are very light and I don’t think that you are skinny fat.
So I guess you have about 4 months left maybe, for preparation? I would split it up into a strength phase of about 3 months and a more sport specific phase of 1 month. Since you are a absolute beginner I recommend you check out Rippetoe’s Starting Strength to learn the movements the correct way and start implanting his basic training approach. Don’t freak out, he has some benching and over head pressing in there but this won’t hurt you. If I was you I would just stop pushing the bench press as soon as you can bench your bodyweight and do 10 pull-ups with good form.
During the strength phases, just concentrate on the lifting, since you are new you will make a lot of gains fairly quickly. Just eat healthy (don’t under eat, being all afraid of gaining “soooo much weight”) and lift heavy as far as you can. Do some tempo runs during the strength phase, maybe twice but not more than 3 times per week for low volume. You can go the full distance though (400m) if you want to, just keep the volume between 800-1200m.
