I am about to embark on a carb rebuild, anything I should know before i start?

Tag:7002050 JO
Throttle body:7002105PF in big letters KF8

I haven't gone for a rebuild kit. what will I need that doesn't come with the kit (any additional gaskets?) am I likely to find this at NAPA, or do I need to look somewhere online? any difficult to dis-assemble or re-assemble parts?

thanks in advance for any tips.
