Hey! Saw your post in PGen and thought I'd throw some hints your way ^^
1. Wartorle is a good choice!
2. Alakazam is an awesome choice, if you have the means to trade and evolve it. Otherwise, Kadabra works pretty fine but Mr Mime (trade with an NPC) is awesome.
3. Paras isn't supergood actually. Victreebel or Vileplume are better if you really feel like you need a grass type.
4. Pidgeotto is good for being able to FLY anywhere, but other than that you might be able to switch this for a ground type or electric type like Magneton or Raichu, they are pretty good :3
5. Growlithe is surely a great fire choice.
6. For the last spot I'd say go with Hitmonlee actually, or Machamp (once again if you have the means to trade to get it). A ground type is useful in Kanto, but it has many weaknesses. A fighting type will be very good against the Elite 4 in the endgame :3
Those are just my opinions from playing the games a thousand times, others probably think a bit differently. But hope it helped!
