I voted minigames because my clan is a general all-around skilling clan (eg we're not a combat clan), so minigames are fun. Combat minigames *can be* fun, especially when geared towards skillers such as miners vs. wc'ers (pickaxes and hatchets only) in Castle Wars or Clan Wars and of course there are skilling minigames such as Stealing Creation (<3).
What slayer master to use is based on combat level. Check your in game guide or a slayer guide on the forums or here on Tip.It to see what master requires what combat level. A handy quest for slayer (especially if you plan to train it for a while) is Smoking Kills. As soon as you can do it, I highly recommend it as it will give you access to all sorts of handy things (slayer points!) like being able to block tasks you don't like and abilities and gear you can't get without said slayer points...and the points will not only buy ablities, but gear (including runes) that can make you some pretty nice money when all is said and done. When I was going for 99 slayer, I made about 20m off my points alone. So, Smoking Kills...very worthwhile quest.
