I'm going to do either a Ranger or Gondorian Knight at some point...always best to start with what's closest to your skin; the clothing. Under garments are fairly generic to Medieval or Renaissance standards; Rangers were primarily leather garments and armor, mostly in the form of longcoats and bracers...I believe Aragorn's longcoat had reinforcing leather on the sword arm.
Gondorian Knights were akin to 16th Century High Medieval knights in full plate but of course, they were much more artistic having taken many design cues from the Elves.
For my Ranger, I was going to go with a leather breast plate, vambraces and greaves over leather pants, long boots and some sort of long-sleeved tunic.
As for weapons, mostly sword, bow and dagger/knife...the Gondorian knights may've used spears (no mention of lances that I can recall), the Rohirrim certainly did- as well as some really nasty battle axes, with a Danish look to'm iirc.
The Rohirrim royalty (Theoden, Eomer, Theodred, Eowyn) wore highly detailed leather-embossed plate, but the rest wore primarily leather armor and garments; of them all, the Rangers and Rohirrim should be the easiest.
There is a Gondorian harness for sale on eBay or there was...I shall look for it later, my PC is prompting me to shut down now to apply updates. PITA this thing is. lol
