I'm not too keen on the bosmer, unless they've become more "badass" in Skyrim...Oblivion pretty much turned me off to them, haha! I would mainly focus on stealth to get around unnoticed, with archery to soften up baddies, then go in for the kill. I'm thinking either dual wield, as in a Drizzt type character, or single blade, no shield, as in an Aragorn/Strider type character. Other skills (speechcraft, ect) are not as important. Alchemy would be good to have, I'd imagine.
Well, if you're going for a D&D/Tolkien type classic ranger, alchemy would be essential. Remember Aragorn used the King's Leaf or whatever the herb was called on Frodo's wound from the Nazgul blade. I've never used light armor, but I'd say sneak, one-handed, archery, light armor, and alchemy would be a wise selection, giving you versatility without spreading out too much. The only downside is that you're giving up three potent defensive skills: smithing, heavy armor and block. If you give up all three of those, I'd say you need to consider some Restoration (possibly not what you want for your character type) or possibly Alteration for the X-skin spells - and again, this might not be the kind of character you want.
Alternatively, you could focus like a monomaniac on improving your stealth and archery skills, and add in some poison-making skills to improve your chances of one-shotting enemies, or at least preventing them finding you until you've turned them into a pincushion - a
dead pincushion hopefully. In short, if you take neither magic school, and you give up the three big non-magical defensive skills (block, smithing and heavy armor) then you'll need your ranged offense and sneak to be one hell of a defense for you. Otherwise
you might start getting one-shotted. I'd also learn to be patient, especially with groups of enemies, and possibly consider working at night to decrease your enemies' ability to see you.
For the cleric, block makes sense, if I'm using a shield. Not sure what disabling spells are in the game, but the focus might be restoration, conjuring, and pummeling.
You could basically choose three or four combat skills: block, one-handed (mace, for the old-school D&D authenticity) and restoration and conjuring, and swap between them as necessary.
Ask one of the more magic-experienced people if wards block non-magical damage from melee weapons and arrows. If they do, then you might not need Block, at least if you have sufficient magic.
EDIT: Also I meant to add this: If you're playing a
good cleric, you'll have to think about conjuration. I don't think you can conjure anything except Daedra and the Undead. The Undead of course would be out of the question for any good character, and only suitable for the Evil Priest or Necromancer types, but even with the Daedra it sounds more fitting for mages or evil priests. Good mages can get away with summoning evil otherworldly creatures and forcing them to do their bidding, but if you're looking at an old-school D&D cleric type, who gets his magical power directly from the gods, what good god is going to grant their servants the power to summon evil spirits? Seems like they'd be more likely to send good spirits to aid their servants instead - yet there seems to be none such in TES, at least as potential summonees.
