craftgrrl | Archival inkjets, giclees, whatever...THINGUMMY

I have a question for those of you who sell prints of your work. I'd like to do archival inkjet/giclees of some of my drawings, so how have you gone about doing so? I have some general questions.

1. I normally scan things to .tif at 300 dpi for storage/internets, but I get the feeling that's not high enough to produce quality prints. What's preferred?

2. I've been looking at archival papers, and the Crane Museo seem really nice, unless someone has a better recommendation.

3. And where are you getting your prints done? At home on your very own Epson, or at Kinko's, or at some really good internet printer?

4. I've seen pricing anywhere from 15 to 65 to (gasp) 250 for a single 11 x 14. What pricing do you find fair? I feel like anyone who pays 500 bucks for a Picasso giclee is getting ripped off, and all I'm hoping to do is have my art be affordable to someone who likes it, but ain't payin' for an original.

And for examples of what my drawings look like, for reference:

The last one's a drawing of Neil Gaiman's Death that I gave to him at the Anansi Boys signing, so that'll never be printed, but I rather like that drawing. (He kissed me for it! /fangirl)
