Good start, Dave
Try for Omega Centauri (globular cluster). I think you will struggle to see galaxies such as the Sombrero and Centaurus "A", but try.
No instructions in your manual on focussing the finderscope? Many have a locking ring at the rear of the objective holder. If yours is like this, then turn that to back it off, then you can turn the objective holder. This adjusts the focus. When it seems right, screw the locking ring back up to meet it to hold it in place.
Yes Telrad beside the finderscope. If you are using a Telrad, then a right angle finderscope, rather than a straight-through, is all you need. Use of the Telrad should place the object of interest into the field of view of the finderscope.
