A true resource site shouldnt need to use referral codes to make money from the people visiting it.
IMHO its bad advice to use referral links on a resource because it makes it seem like you only give GOOD advice about sponsors that make you money
Of course that fact you are starting a 'resource site' yet come here asking for the types of thing webmasters should be asking you about doesnt look to good either.
Whatever happens good luck with the new site
