Is a pin type adjustable spanner wrench , 1-3 inches what is needed to adjust the head bearings?

Really shouldn't be a need for a wrench like that. I'm not even sure if there would be room to use it.
Tighten with hand power, and then if you need to snug them up more, tap on the indents in the nut with a pin punch. You could always use a brass pin punch or drift too.
You just want to bring things up snug where you get the shake out. Double check your initial pre-load again after you tighten the top nut.

Once you loosen the top nut , or stem nut, you can use a pin punch to tap the star adjuster to tighten or loosen the bearing load. Make sure you loosen the fork pinch bolts ( or nuts) . Bike level, front wheel just off the ground, tap the wheel to the side to the left and right and see where it starts to fall away. Adjust acordingly . To tight it will weave , and feel heavy at slow speed , to loose it will wobble at high speed, and on decel you notice it about 30-40 hands just off the bars. Tire pressure can also effect this, as well as cupping and wear patterns. If the neck is adjusted to spec, and you get a wobble it's most likely the tire. A properly adjusted fork will really make the bike feel right.

Thanks for the tips guys. I guess my real question would be , what tool was meant to be used to tighten/loosen the cone seat?

Just hand tight, and a little tap with a pin punch. Once the top nuts torqued , you can determine where it needs to be.
