The best way to include a photo is to post it somewhere on the web and link it in your Forum Post.
From the insert menu you should be able to insert both audio and midi tracks.
There is a type of all in one synth track, but I don't usually use them. I like to have a separate midi track from the synth.
I usually add soft synths using the insert synth and then follow the prompts to select what I want. Don't select single instrument track if you want 2 tracks.
