Hi. Your planned trip/adventure sounds great. So refreshing to hear about people coming to the range to do a cool alpine traverse, rather than one of the classics (Cosmique arete, Chere, Tre Monts, and so on).
One of the best book I have read about glacier travel and crevasse rescue, and alpine climbing in general, is Mark Houston and Kathy Cosley's "Alpine Climbing: Techniques Take You Higher."

In can't recommend it highly enough. In particular, their emphasis on placing stopper knots on the main rope, and hauling on a separate strand, make very good sense for a party of two on a glacier, especially for a year like this year, without substantial snow cover.
In terms of hiring a guide, I once hired Kathy Cosley for just that--to work on rope skills and crevasse rescue. It was well worth it, and my time with her changed the way that I navigate glaciers.
If you decide to hire a guide--great--but I would say, perhaps even more important, is that you and your partner devote some time to talk through different scenarios, and practice your systems, on your own. You don't even need to be on snow or ice at first--just a grassy field or slope works fine. You can rope up like you would on a glacier, self arrest, flake out your coils, set up your hauling system, and so on. You should know what you will do, or try to do, if you or your partner fall into a crevasse. Discuss, practice, train. Have a plan. That will go a long way toward making your traverse as safe as possible.
Regarding gear, I would wait before buying lots of stuff (pulleys, rope capture device, and so on) until you practice some of the systems, and decide what works for you.
And again--it sounds great. Go for it!
