Initially stick to the basics rather than more advanced methods.
In essence to go from your original part to a finished carbon part, you will need three main steps:
Making the pattern - the thing you take the mould from - often a modified original part.
Making the mould - what you lay the carbon into - in basic terms its a reverse image of the pattern
Make the part - Wet lay / hand laminating is the best starting point.
This is a good basic video on mould making. You can see a simple part is lightly modified on a base plate to use as a pattern for the mould.
This is a good video on basic wet lay laminating into a simple mould and the resultant finished part.
Get the basics sorted and once you understand the stages you can move onto different techniques and materials like resin infusion and pre-pregs.
