Rugby Kicking In General

Question
I'm an 18 year old fly half and I am just about to make the step up to senior level. I am currently spending a lot of time practising my kicking skills to hopefully get noticed by the coaches, however I am struggling with a couple of variety of kicks that I would appreciate a few pointers with. Firstly drop kicks, at goal I can hit them well from the half way but my question is how should I vary my technique for restarts where ideally I'm wanting a lot of height but to limit the distance?
Second up is spiralling the ball. I am able to punt the ball a good distance but am aware that to achieve optimum distance in a kick is to spiral. I am hopless at this, always just slice them or don't get a clean connection. What angle should I be looking to drop the ball and with what part of my foot should I be making contact with the ball?
Finally, kicking penalties/conversions. I find that from short distances and easy angles I can make get most kicks but I never seem to achieve a good connection, so where should I make contact with the ball and with what part of my foot?
Thanks a lot in advance for reading this rather long question, and if you can supply any helpful tips I genuinly appreciate it.

Hi Daniel

As a prop I really suck at kicking but I find You Tube has some really good stuff.

I went to You Tube and searched: "how to rugby drop kick" and got a list of "how-to" videos and examples of the pros doing it. Here is the link to that search but try yourself...
