>>1643396very charming bike.
glad you got it.
One upgrade I would consider right away, is a pair of nicer pedals. Black, nylon BMX pedals with high quality bearings. Fooker for example. Tools to change are a 15mm spanner, some grease, wd40 (or equivelant) and a rag. Pedals unscrew towards the back of the bike. Slip a pipe over the wrench if you can't crack them. Grease the threads of the new ones with your fingers. Be careful not to crossthread and install them quite hard. Clean the threads in the crank out with a rag and spray before you install.
