Well, all skills are good since the game supports all kinds of characters.
So what 마이클 said at point A doesnt make sense at all since security is used for lockpicking -.- and speechcraft is awesome if used correctly. B makes sense cause what can diplomats do in "hell"?

and C, well its hard to get all skills maxed out so dont do that

enchant your armours and rings,amulets whatever so they increase the skills you want better (btw this is end game

) As for character creation, create one that is fun to play! I would make a ranger type character, uses bow to inflict massive damage (owns if used with sneak) and up close you whip out your huge two handed sword!!! gets em everytime

I would also take illusion magic as a minor skill, so i can be vanish and backstab!

well thats just me

So just make sure you use all your skills, otherwise its a waste...
EDIT: lol i wrote minor ^^ been playing morrowind lately
