Well done on getting out and using the scope. Jupiter is quite low at the moment which means its light has to pass through more atmosphere than is normally the case, which can make seeing the bands a bit harder. In a small scope they can be a little subtle so keep trying.
With Orion you most likely saw Orions Sword. The Belt is the 3 bright stars in a row to the north (below in our orientation) of the Sword. As the Belt is quite large it would struggle to fit in the field of even a small scope. The Sword on the other hand consist of several nebulae and clusters the most obvious of which is M42.
With your red dot finder, I assume you have fiddled with the 2 adjusting knobs to move it. If it is still out, check it is sitting properly in its bracket and then see if the bracket itself can be tweaked. Be careful using tools (screwdrivers etc) on the scope, set the tube horizontal so you don't drop anything on the mirror!
An EQ style mount can be a little tricky for a beginner, which is why I and others (not everyone I may note) recommend a dob as a beginners scope. Unfortunately I am unable to offer any advice, not having used an EQ mount for many years, beyond saying that good polar aligning is essential.
Anyway, keep at it and hope to hear more reports soon!
