If you use the x64 release, you can use the new GM tool to set those skills to maximum. I used mostly ingame methods to do that, such as adding those item shop tickets for expanding the amount of crafting skills I can have at a certain maximum level. For the quests, I simply added the requested items too. Might not be as fast but it works too.
If you don't use the x64 release, you better check the thread about it and ask one of the more known users if they have a link ready.
