I was tested for the MTHFR gene and it was found to be normal. Does that mean I definitely don't have problems with methylation, or are there other SNPs which can have an effect?

Yes other SNPs can have an effect. You'd have to get a 23andme test or similar to find out your other methylation SNPs (and a lot of other ones).
Have your read ahmo's methylation for dummies? You might want to start there:
