Yes for artmoney, just start it up, then start the game, alt+tab out once your game is loaded and you can see your character.
Remember the value of whatever it is you wish to find. The more you have to work with the easier it will be!
Next step is go into artmoney, select the game from the little drop list right in the center more or less.
Then do a search for the value of what you are trying to find (ie: 5 skill pts, 50 gold, etc)
Now, when it comes to doing a search, different games handle themselves different. So sometimes it might just be a integer search, sometimes its a floating number, sometimes you need to do a "All" search.
In our case though, most of the numbers are standard 4 integers (I think gold might be 1 or 2 I forget). In any case, just do a integer search and you shouldn't have too many problems.
At first it is going to come back with tons of results, anything from a few hundred, to a few million. So, go back into the game via alt+tab, change the value by either dropping, spending, adding, subtracting, etc (so long as it's different) then alt+tab back into artmoney and repeat sieve function until you are left with 1-4 choices (sometimes it takes 1-4 tries to get it that low).
Once you get your values, set the names so you remember what is what, edit the value to whatever you like (remember, gold takes 1 value to make perm, skill/spell points take 2 values!)
Xp / Attribute points I have no clue, I haven't figured them out yet (course I havent played the game in some time either hehe so).
Hope this helps
Cheers.
