Chris, first ditch the moss, it doesn't belong on a scheff. and will either compete for water, or else keep the tree too wet when it shouldn't be. If there's a layer of stones glued to the surface, pry it off and discard it... it doesn't belong there either (only there to hold barely rooted plant/cutting in the pot for transport). Now, first I suggest you learn to keep your tree alive for a few mos. before even thinking about doing anything else, because whatever you do (as a newbie or not) will stress it out, and it's got to adapt to your environment which takes a while, and you need to figure out what its needs are water-wise and light-wise and humidity-wise, etc. Believe me, it won't grow that fast (spring's over even to an indoor tree) that your learning curve will outpace it. Give it good light, don't bother to spray it as that's a waste of time, though a wide tray of stones and water underneath where the pot never, ever touches the water, will help humidity, and water only when a lot of the soil is dry (not just the top to a touch). Start reading about growing things, about your tree and about bonsai, and don't be chopping things off it yet. Good luck.
