You really can't buy the cams yourself since you won't know what size you need BUT I can say I'm just about 100% positive that the biggest ones will work for you. On top of that, may alignment shops don't stock the bigger Cams. The biggest you can adjust out is 2.75 degrees on the 4x4. The cam that does 2.75 degrees for the 4x4 is the same Cam that will do 3.5 degrees on a 4x2. If you have too big of a cam they can use the left over adjustment and apply it to your caster since we know you changed that too. The biggest Cam SPC makes is the 23194 which is 3.50 degree 4x2 and 2.75 degree 4x4. There are other brands too...
As for the toe, that is caused by your tie rod ends. When you lifted the front the distance between the pitman arm and the steering knuckles increased but you didn't adjust the tie rods.
The Toe they will be able to adjust. The Camber/Caster is another story.
The real question will be, what condition are your front springs. If they were at new factory height and you added 2" spacers I don't think you would be able to align it. If your springs had sagged say 3/4" over the years then yes, I think it will be align-able, although you'll need the bigger Cams.
Oh yea, 2.5" lift kits and up comes with brackets will compensate for the Camber and Caster change BUT, even then, your toe will go way negative until you align it.
