i think you could get ok results just by looking at what some photo looks like on your monitor and what it looked coming from printer, then try to find sort of safe zones for adjustments for brightness/contrast and color vibrance.
i made one print few months ago at this local shop, and it gave me bit too dark photo. next time i made some prints, i just adjusted for bit too low contrast and added a hint of brightness, just so much that it didnt look like completely crap on my screen, but looked just a bit off and the prints came out great. but the vibrance was still just a hint too low(first time i printed it was bw photo) on color prints, so next time i print, ill just add a hint of extra vibrance for color photos and it should be fine.
prints will naturally always look bit different than what it looked on your screen, simply because prints reflects light from ink and screen emits light, also the surface of print is different from your screen.
i suggest printing some color/brightness/contrast chart and see how it differs from your screen and adjust the photos according to it. but i suggest leaving the blacks just a hint more black(than you think would be the optimum) when printing, so that you dont overdo it and get gray blacks on the print.
I've been just using about +40 brightness and it seems to do the trick for the most part. The color is still a little off, maybe a bit more contrast would fix that. Thanks for the idea though, I had not though of just printing off a chart to compare.
