Some tuning questions

So I have my truck where I can drive it down the road now, but it's still having some issues. I am totally new to the tuning world so I guess my first question on this is which table do I start with first. Since I am working with fuel only right now do I need to put in any spark table parameters? Should I tune with EGO at 0% authority to start with? Should I adjust the AFR table or leave as is? Right now it seems as though my tune is pretty much keeping me rich throught the drive with a little leaner condition at cruise. I have read quite a bit in the manual but it doesn't seem to give you much guideance as to what goes first. Below is my current msq and two datalog's I ran this weekend. Any advice would be appreciated. Oh yea I am using the registered version of TS w/ VE analyzer live letting it do the tuning

Vehicle specs
1989 toyota 4x4 w/ ford 302
1992 GM TBI 55 lb/hr inj
MS2 V3

No.

I would.

As you are using a combined air/fuel table, I would set the AFR table for what you want your AFRs to be, then tune the VE table to hit those targets. If you don't like how it runs at those AFRs, go back and change the ARF table.
