First of all, thanks everyone for your expert help!
As far as framing goes, I have used a company called Frame Destination ( http://www.framedestination.com/ ) for years. You can buy high grade packages from them and quite easily do the framing yourself with professional results. Find a good source for ink - you'll need it.
Peter, by "a good source of ink" do you mean the shop that sells the ink at the cheapest price or would you suggest inks from other manufacturers than Epson?
Congratulations on the move to making fine prints of your photography, Wawe. Printmaking is an art in itself and brings its own joys and rewards (along with the occasional frustration).
I've tried to prepare myself for the frustration part, at least...
If you're deeply committed, as that 4K Eizo might suggest, I'd recommend you add a viewing booth, a la http://www.gtilite.com/products/desktop-color-viewing-stations/pdv-professional-desktop-color-viewers/. Make sure you get one with a dimming knob (very important!).
Thank you, Jager! I'll definitely have a look at the viewing booth options (with a dimming knob).
I would disagree here. I think starting out w/ expensive EEF (exhibition fibre) when you're first getting your sea-legs is an unnecessary expense (and it's full of OBA's so that adds to the fun/complexity). A classic recommendation is 'get a sample pack or two' so yo learn the differences between papers and can hopefully zero in on the kinds that you think you'll like.
I'm with Howard. Get a decent quality RC paper like Ilford Prestige or Epson semi-gloss, use the canned profiles, which all seem much the same for those types of paper. Your cost per print at 12x18 on 13x19 paper will be about 4€ or $4 per print... and you can just thumb-tack them to a wall to look at them for a bit. You will already find the prints are impressive.
Leave the decision about baryta or matte or whatever, and the complications they bring to colour management, for later.
So is the correct interpretation of these two comments that there are some papers, with which I'll more easily get the prints to match what I see on my screen than with others? If so, I might want to start with the easy way, moving on to the other choices once I've got a little more experience.
Now, all of that said, again I come back to the display 'issue'. You mentioned that you will probably eventually step up to an Eizo display(big bucks), and if that is affordable, definitely go for it. However, I would like to point out that many of the members on this forum(including myself) have sung the praises of the NEC PA line of displays for a few years now. As a matter of fact, some of the most prominent photographers and teachers of the art have been using this line of displays for at least the past 5 years and more. I purchased my first NEC approximately 7 years ago and have never looked back. I now have 4 of these displays in various sizes and the first one is still working and calibrating well. These displays are less costly that the Eizo and seem to be very comparable in quality from all reports. Visit their site and see for yourself -- http://www.necdisplay.com/category/desktop-monitors. I hope this helps, and have fun with your new printer Wawe.
Thanks for your comments on the display choice! I've understood that the color reproduction and other properties relevant for post-processing and soft proofing etc. are second to none in the Eizo I'm considering. Not to mention the "true" 4K, 31.1" size and other nice features. But most of all I find valuable the integrated calibration device, which I remember reading you could set to calibrate the display, say, weekly and never worry about it anymore yourself. It's ridiculously expensive, though, there's no denying that.
I have never owned a display from NEC, Eizo or any other of these top-end manufacturers. I think I can stretch the budget even for the Eizo CG 318-4K (and not get too much buyer's remorse), but my main concern, if I decide to do so, is how long will the product serve me. If I would have to buy another display in, say, five years, I'm not sure if could justify the purchase. If anybody has knowledge (tests, reviews etc.) on the expected lifetimes of these ultra high-end monitors, please let me know.
