I should have asked this also but I did everything and then seafoamed. And your correct half vacuum and half in tank.

Your supposed to add to oil too. What id do is do everything your suppoed to, then oil change for after when you drive it.

How often should seafoam be done.
Not trying to jack thread just asking quick Q

Some use it every 10- 15 thousand miles , I use it every 50k , but as stated before you change the oil and plugs

I am pretty sure you are supposed to change your oil after seafoaming. As for the how often, it depends on you. Do you use crappy gas all the time? If so I would seafoam at least every year. I typically only run certain fuels, exxon, sunnoco, or shell, and i run fuel injector cleaners often so once I am done cleaning the engine up from the previous owner I may never use it again.
