Building my pokemon heart gold team advice?

I just bought Pokemon Heart Gold about a week ago and am trying to build a good team. So far those that I know I want to keep on my team are my Jolteon, Arcanine, feraligatr, and maybe my togetic (which I will evolve to togekiss). What pokemon should I add to my team to make it as good as possible? I was also thinking maybe Abra which I would level and evolve, but Im not quite sure. Moveset suggestions will also be valued. This is my first pokemon game so I'm pretty excited. Thank you.
