Yer welcome!
A point of warning though. Fallout 3 is still an action RPG...which means you'll need some kind of combat skill. It doesn't have to be astronomically high or even tagged, but you can't get by -completely- with noncombat.
Sneaking, especially with a Stealthboy, can make things easier. A stealthy headshot will decapitate just about anything, and if your target is alone when you do it, you can often not attract any more attention. This makes it possible to sneak around assassinating folks.
You can also just sneak around, but without a Stealthboy there will be places you can't go without exposing yourself, and the Stealthboys are limited use items. Hacking helps, but not every location has turrets and robots to use...and robots are pretty fragile, and probably won't singlehandedly wipe out your foes (though they make terrific distractions).
You can sometimes surrender to enemies by holstering your weapons, but I haven't tried that. Not sure if Speech skills come into play there or what.
These skills are all very important, don't get me wrong, but they won't make combat nonexistent. Just easier.
