BadgerAndBlade has a very detailed section on what to buy and how to go about shaving with a straight. It's not that hard at all. There are things you need to remember though.
You need a very sharp edge, stropping is essential. So you will need a good, quality strop. I would go with a 4 sided paddle strop and use 3 grades of diamond paste on three of the sides and straight leather on the last. This will keep you going for a long time between hones,
I wouldn't bother honing your razor yourself until you get comfortable with the rest of the process first. Send your blade to a honemeister (not to be confused with a knife sharpener) or buy it presharpened from a well known razor distributor. Honing a razor is a lot different than sharpening a knife. A razor only needs to be honed every 6 months or so - especially if you are using a pasted strop.
Next is the soap. A nice brush and some Proasso is a fantastic way to go. I love that stuff. There are tons of shave soaps and creams to try which is what makes this fun.
When shaving remember, this freakin blade is sharp!! No pressure! If you shave with a Mach 3 or something similar you use a lot of pressure to get a shave. This same pressure will remove your face with a straight. This is also why you will get a better shave with the straight. Very light pressure means you are cutting the hairs, not your face. Your Mach 3 or whatever, forces you to use a lot of pressure which causes burn and ingrown hairs.
It takes some time to get used to a straight, so don't expect a perfect shave first time. It will take about a month to find your technique.
Best of luck!!
