Question 1988 3.9L Tune-Up Advice?

I have a 1988 with only 71K on it, so I want to do the best tune up I can. The oil was just changed last year, just cheap store brand oil (Autozone or Advanced Auto). Is it too late to switch over to a fully synthetic oil?? Maybe if I flush it out before I switch it over with something??

I'm going to change the spark plugs, what are the best? Would anyone recommend some sort of fancy crossfire 4 way plugs?

K & N air filter of course...

Is it too late to swap my transmission fluid over to full synthetic too?

I need to replace my radiator anyway so I will drain and fill with some sort of Prestone.

Should I Seafoam the engine??

Thanks

the oil was changed last year? you know its like september pf 2011 has the truck been run alot ot has it sat? and you can change to synthetic at anytime it wont hurt anything and when was the last time the tranny fluid was changed and it was flushed? prolly never if it was me id have it all done and unless your building a stout engine your only gunna waist money with thoss 4 point star fire bullshit plugs and if its been sitting flush the block out with a garden hose and get that crap old coolant out and fresh stuff in

Yeah it was only driven on the weekends or to the parts store down the street, it's only got 70k (1988)

I don't think the trans fluid has ever been changed, is that ok to go synthetic too?

What about Seafoam? I can't see how it could hurt any...

Before I go back to replacing fuel lines, I figured I would get new plugs and try to clean out the fuel system + jets/carb with Seafoam recommended by a mechanic. So I put one can in half a tank of gas, haven't seen a single puff of smoke yet. Says one can per 8-25 gallons of gas, so I figured one can to a half tank makes for a potent mix. I was told stock plugs were copper tipped, so they set me up with some Bosch Platinum Plus. It has stalled out since the Seafoam application, so with these plugs we will see if it still has the problem by the end of this tank of gas. If it continues I have to choose between disassembling the carb or replacing my fuel lines again, when it has this starting problem I noticed the check engine light flashes on and off while I am cranking, but not when you start it without the problem...

Are these anything I should consider replacing, they look like filters?



There is a black thing connected to this one with a hose:



Another on the back of the carb:
