Raising front end / Wheel alignment

If you have the resources then by all means, go out and have it all gone over.
I do my own alignment and adjustments and my tires last for years of daily driving (well, the front ones anyway):D
Point is, I change mine an inch up or down sometimes with zero difference in handling or tire wear at all that I can tell.
Of course if your tie rods are fairly parallel to the ground it's no risk at all to change an inch, but if it's already lifted enough to raise the inner end of them an inch over the outer ends then that adding one inch of lift can change things more drastically.

If the tie rods are fairly level with the ground now, then an inch of lift isn't going to hurt a thing with the alignment.

Tire wear isn't the only thing to consider though. Camber doesn't start causing noticeable tire wear until you're well over 1* in either direction. Caster basically doesn't cause tire wear at all regardless of it's setting. Toe is the only thing that causes rapid tire wear, and a small change there makes a big difference.

But a couple degrees of caster will totally change how the car feels out on the freeway, from squirrely to stable. Buddy of mine just went from +3 to +5.5* of caster on his '66 mustang, it has a totally different feel on the freeway. And if you've got manual steering a degree or two of caster will change the steering effort enough to notice too. Going from -.5* to +.5* on the camber will give the car a different feel in the corners if you do any kind of spirited driving, even just at the "having fun in the canyons" level. Neither of those will have any effect at all on tire wear. Now, both of those examples are a bigger change than you'll get adjusting the ride height by 1". But if all you're doing is judging by tire wear, you wouldn't notice them at all. I think a lot of people chalk some of those handling issues up to "being an old car", when the truth is that half a degree here or there on the alignment makes a big difference in road manners. No it's usually not critical stuff, but it sure makes driving them more enjoyable.
