You can actually make your own landing gear using some stiffer music wire from a hobby shop/online outlets. Take a look at the FT Mustang (not the Master Series, but the earlier version) or the MiG-3, as to how the landing gear is installed in the wing. You'll likely have to bend the wire a little more so that the landing gear has the wheels coming straight down rather than at an angle, or else the plane will not track properly on landing.
As for the tail, you have a couple of options - either use a small tail wheel (like that found on say, a UMX Timber, or the FT Edge) or a tail skid. I've used a barbecue skewer to make a steerable skid for the FT Bushwacker by laying the skewer along the bottom of the rudder and making it a little longer than the rudder itself, so that it kept the rudder up off the ground. The only issues I've had with barbecue skewer skids is that a semi-hard landing will pop it loose from the bottom of the rudder if not secured well with glue (and sometimes a piece of tape), and the skewers get worn away fairly quickly rubbing around on the ground.
