Not sure if there have been exact answers to everything yet, so I'll just answer anyway

1. what's the purpose of the little hose coming out of the bottom of the bike? im guessing something to do with the gas tank but cant quite put it together my self
I think you'll find it's the overflow for your tank. If you open the tank cap you'll see a little hole on the rim (ie not the big hole you put fuel in) - that leads to that hose.

As I think others have said, don't bother. If you ride other bikes too and do it by habit (or need to learn to do it by habit for those other bikes) then go ahead. But it's not necessary.

it says if the engine is hot i should open the throttle half way and start it instead of choke
Probably already answered I think - but I always tried without the throttle first, then if that didn't work use a bit of throttle. Half way throttle sounds a bit steep though.

?
I think Rob answered this already - should rest as it is, and the only downside of overlubing your chain is the mess it might make flinging off. Probably considered norty by some, but the way I lubed the chain on the gpx was to put it on the centre-stand, start it up, put it in gear and let the clutch out - then spray the lube over the chain as the rear wheel turns for 4-5 seconds. You should get reasonable coverage doing that - just keep all appendages clear of the chain for obvious reasons.
To check if the chain's too loose, see how far up+down the bottom stretch of chain moves at the centre-point between the sprockets. It should be around 20-30mm.

I think some adjustment is necessary here - though exactly where the friction point should be is a bit subjective.
The gpx doesn't have an adjuster on the lever, but it has a thread adjustment at the other end of the clutch cable - on the right side of the engine near the bottom (on the clutch cover). You could play with that and see how you go, or get a knowledgable mate to help.
It could be that you need a new clutch cable too - it may be stretched and at the end of its adjustment range.

If you have no fear, you're not going fast enough.
Never argue with an idiot. He'll drag you down to his level, then beat you with experience.
