DPPt/HGSS Heart Gold team

[Electivire54]

Ok, I'm working on a team that I want to play through Heart Gold and I'm not sure if it's a good team. The Pokemon are as follows:
Typhlosion: Flame Wheel, Eruption, Solar Beam and Gyro Ball, or Earthquake, Focus Punch or Rollout.
Forretress: Rapid Spin, Gyro Ball, Explosion, Protect or Poison Spikes
Heracross:Close Combat, Megahorn, Brick Break, Aerial Ace or Take Down, Reversal or Focus Blast.
Skarmory: Fly,Steel Wing, Flash Cannon, Swift, Night Slash or Aerial Ace
Smeargle: Rest,Surf,Sleep Talk, Transform
Ambipom:Double Hit, Last Resort, Thunder Punch, Iron Tail

So If anyone could give me tips on their attacks or something.. Thanks!

As far as in-game goes, anything works that isn't a team of six Magikarp. Anyway:

- Typhlosion gets shafted horribly as far as movepool goes, but luckily his decent Attack stat can help him out. Fire Blast or Flamethrower will be the best attacks for him to have as far as Fire goes, Earthquake's a decent option but Gyro Ball will be near-useless on something as fast as Typhlosion. Sunny Day + SolarBeam, if you can get both of them, is a decent option as well.

- Forretress won't need Rapid Spin in-game - competitively, yes, but here it's just a weak move that serves little purpose. Zap Cannon and Earthquake are Forretress's best options for attacks, alongside STAB Gyro Ball and (I think) Bug Bite as well.

- Heracross would like a Rock-type move in place of Brick Break, or even Night Slash will do well for Ghosts. Take Down and Focus Blast won't work too well here, and Reversal's a bit limited in-game as well.

- Flash Cannon and Swift will be useless on Skarmory since the metal bird's Sp.Attack is complete garbage. Otherwise, all your listed moves are viable - Swords Dance is also a good option to run here too.

- Smeargle loves Spore - the move is very much standard for Smeargle so if you can get it, then do so. Otherwise, Smeargle's best working as a supporter - his offensive stats are atrocious, but since he learns every move in the game bar a select few, just stick together four moves you feel your team would benefit from to make your set.

- Fake Out kicks ass on Ambipom, and I'd highly recommend it if your ability is Technician. Last Resort's a bit meh in-game, what with Pokemon Centers around every corner, and Iron Tail's crap regardless. ThunderPunch is good though, Double Hit can be an interesting option, and moves like Brick Break and U-Turn can come in handy too, as well as other Elemental Punches Ambipom can learn.
