Increased creatinine levels don't necessarily have anything to do with creatine.
The kidneys not working as normal can cause blood levels of creatinine to increase. A test for creatinine levels is sometimes done with a BUN test to check for kidney fuction.
Gout is often caused because of high uric acid levels (in the blood), sometimes when the kidneys are not able to filter it well enough. So, it certainly sounds like you've got some issues going on with your kidneys.
Drinking cranberry juice can help the kidneys by increasing the citrate concentration. There are also a ton of drinks and formulas designed to "cleanse" the kidneys, though I can't vouch for how well any of them work. Drinking lots of fluids in general will help as well.
