Khajiit assassin-type here too. Definitely work on your stealth and sneak attacks to get those perks. The sneak-archery boost is nice, but the backstab will really allow you to take down enemies easily. Do your best to stay hidden. Be patient, and don't be afraid to run. When in combat, I would always have to remind myself to always stay moving. You can see most attacks coming, so make sure to strafe or drop back out of distance. I would usually be able to take down most melee attackers this way. Archers and magic users were always the worst for me until I built up a decent magic resistance. For archers, you can still avoid being hit by keeping moving too. Also, in general, the vanilla game at least is almost comical in that enemies will forget you just hit them if you can hide again. This is often helpful to take someone out with your bow from a distance. I would play using a dagger in my main hand and a spell in the other (either healing or a good destruction spell). Once a fight devolved into a melee affair, it would be time to take out a good sword or war axe I kept around for bigger damage. For the most part now, I just stick with my dagger unless a huge brawl breaks out, then just conjure a bound sword. Edit: like was mentioned above, conjuration is not a bad secondary skill to have. You can summon something to take the attention away from you in fights. They can be frustrating if you're doing a stealth play-through, but followers can be helpful for this as well. Personally, I've strayed towards magic a little more, but Illusion and Alteration can also be helpful to make you harder to detect, calm enemies, or for armor bonus spells.
