Rugby08 modding for 2010-2011 season

[O'GARA]

Now that the international and regional club kits have all been released and are on our tv screens, I want to see them on my laptop screen for Rugby08. i am going to embark on creating all kits for the teams. As I have never done any editing or used photoshop, corel or gimp software I am looking for tips and tutorials on how to do this. i have got a free trial of Corel Graphics Suite X5 but i havent got a clue how to use it for kit modding. tips and tricks are greatly appreaciated. (I am a junior member, so I need some advice on how modding and editing works!)
