Congrats, welcome to the "burned myself on the stem of my Solo" club
attaching to water paths can be a bit restrictive for me as well, since the glass stems don't sit flush in the Solo they let air in. Try putting your stem in and pull it out a mm or two, should help with airflow. Maybe line up the notches on the stem with the air holes?
Charge all the way first time.
Yes you can connect it, PlanetVape is out of the GonG attachments for your Solo, look back some pages for Pipes' picture example and make sure to read my post afterwards with the stem warning. Material of bong is unimportant as a Solo won't differentiate between acrylic and glass, though I prefer smaller pieces myself.
Stop smoking for a week or two and stick to vaping. Vaping is much more efficient than smoking.
