Ranged stealthy carry/nuker? There aren't any stealthy ranged nukers. Ranged stealthy carries on the other hand, Bone Clinkz fits the mold decently well. If you're willing the drop the ranged part though, there's a lot good melee stealth characters. Nyx Assassin is a good early game ganker/nuker once he hits level 6. Gondar aka Bounty Hunter is also an amazing invis ganker once he hits level 6. For carries, you have good old Rikimaru/Stealth Assassin who's ult is literally called "Permanent Invisibility". Also, most ranger-type characters ie Sniper or Drow Ranger can buy the item called Shadowblade, which grants a windwalk on cast, essentially making them a "ranged stealthy carry". If you want the best of all worlds, you got Shadowfiend, who doesn't have an ability that grants him invis but with the mentioned Shadowblade, he can also become a stealthy carry AND nuker. Well, the nukes are a tiny bit hard to land and he's squishy as all fuck until he gets a lot of farm. Generally speaking, good MS don't quite exist on stealthy characters, Clinkz does get bonus movespeed while windwalking, which makes him pretty fast. Also do note that you break invis the moment you attack in Dota2 and the higher the level of play, the more invis gets punished because a lot of the invis heroes are fairly bad against invis detection and at higher levels of play, people actually get detection when against invis heroes. Description of gameplay, farm-levels really really depend on a game to game basis. Some games can drag on into farm wars because you have a team with an advantage but can't crack the enemy defense while the defensive team can't move out because they'll just instantly lose if they take a fight outside of base. In other games, you get 20 minute stomps as you crash into their base because their team composition sucks (or you get to be on the receiving end of a stomp). It really varies. Specs wise, if your computer survives NOTD on low, you'll survive Dota2 on the lowest rendering quality. The differences between LoL and Dota2 is a very complicated topic to discuss easily. In general terms, LoL simplified a lot of gameplay mechanics from Dota. The actual details however, don't really matter until you get further into the games. Overall, things are the same, kill stuff, get money, kill more stuff, win.
