Wheel replacements?

Why do you need to buy more than just tires.
Maybe aluminum wheels, to have that shiny look. I think painted steel wheels look good too.

Chrome or plastic lug covers and hub caps.

Why change the hubs, unless you have a mechanical reason, I wouldn't.

 

If you live in a major metro area, there will be truck salvage yards. You can buy nice looking aluminum wheels for cheaper than what you would pay for new steel wheels. Just make sure of the steers. Some steers are hubcentric, some are not.

EDIT...just saw your pics. Your fronts are good. Just have them polished up. Since you have a single screw, just get 2 aluminum for the drive and put them on the outside.

 

No reason to replace the hubs. They typically last the life of the axle housings (aka almost never need to be replaced).

Unless the seals were leaking or bearings were loose I don't really see a reason to replace the seals or bearings.

Unless the lug nuts or wheel studs are damaged, they're fine.

Myself I'd just pull the steer tires/rims and polish that aluminum up nice and pretty, then put some shiney wheel nut covers and hub covers on. As for the back, I'd do as @TripleSix suggested and just buy 2 polished rims for the outside tires, buy some corrosion discs to put between the 2 rims (steel + alumimum = galvanic corrosion) and then add the chrome caps and wheel nut covers.

 

Your steers are aluminum. They will polish up and shine like new money.

 

I'd be wary of used rims. If you want it easy, buy the rear 2 already polished (you can buy them polished both sides or just the side that's showing).

Machine finish aluminum rims look decent when new but don't have a mirror-like finish. You'd need a couple hours worth of sanding and polishing to bring the shine out. Machine finished rims are a bit cheaper though.

 

Probably need longer studs to put aluminum on the rear

 

From the looks of the rear wheel, you might think about changing those gaskets. They look like they've been leaking. I wouldn't put covers on the steer hubs, those are aluminum and will polish up the same as the wheels with the benefit of your being more likely to check the oil level if there's nothing to remove in order to do it.
