I would suggest a read through this guide that is stickied at the top of the forum. http://www.pokecommunity.com/showthread.php?t=274050
This includes a lot of useful tips and advice on the LP world. If you have any further questions, you are more than welcome to ask me.
In regards to this topic, however, I am going to have to close it, as it doesn't follow the boards rules.
Have a read through the guide and the board rules and then you should be in good stead to post a new thread.
