"The port on the TBI is dedicated to PCV system according to the Howell instructions, it looks to me like it sits below the butterfly valves so I think the TBI getting gummed up by it should be minimized."
that sounds good to me...any excess oil flowing through the pcv will got directly into the intake manifold and burn off in the combustion chamber. If you think you are getting a lot of oil flowing through the system, check the spark plugs.

"The oil filler cap to air cleaner is what I think brings the fresh air into the system. On the stock cleaner this had a little sponge filter but that isn't on my adapter thing on the Edelbrock cleaner. It is inside the cleaner housing so it gets filtered air without fouling up the paper filter."
As long as the connection is 'inside' the air filter, then the air flow from the air intake directly into the valve cover/crankcase will be filtered air which is good. This is how mine (and many) were set-up, but many people remove the hose and just use a breather cap that has the filter built into it. As that is the bypass/breather inflow, there shouldn't be any issue with oil reverse flowing into the air filter housing. So sounds good there as well...

"I guess the port on manifold and TBI are all it has and somehow also vent the area under the valve covers, if that's even possible."
The port on the manifold may go all the way through to the pushrod 'valley' which is connected to the crankcase/valvecover pressure or air circulation. Sound likes its all good to go. Hopefully you are not getting too much oil blowby and trigger an emissions issue....the TBI/O2 sensor should really help keep the air/fuel mixture right which will help minimize too rich of a fuel mixture thus minimizing unburnt fuel hydrocarbons. It should run cleaner than it ever did on a carb - especially at idle. Make sure the engine is nicely warmed up before emissions test, especially if you have some leaky piston rings and valve seals....the heat will help tighten things up a bit, and some run time will burn off any excess oil that might have seeped through the valve seals.
