I use a Dukoff with an open face a D9 or D8 if I can get it, if you couple that with a Rovner (soft leather/nylon) ligature, it gives a big tone that's not too brite and not too dark.
I used to use Rico Jazz 3 hard files, but I have recently switched to Vandorens
I don't soak my reads or clip them. But my boy used to soak his 3 days
I still get trouble with tuning that altissimo G, on Tenor. It really depends on the horn. go to a web site for an easier fingering, just google it. there are about 3 you can use. and always check your pitch on the lower G.
Don't worry about embelishing, that's what you are there fore. I started off accompanying my dad, who plays trumpet. He was always the lead, so I learned to harmonize very well, and make a frame around him. Now I can accompany any singer, chior, or horn player and embellish without getting in the way. Plus most sax players (unlike myself) are soft players, so they really don't have to worry about being in the way. Play as many jazz/blues licks as you want, just make them go with the conversation of the piece. There are only 2 classifications of music.... Good and BAD (sounding that is) -Duke Ellington.
1. Avoid the melody
2. play simpler lines with longer tones, or emphatic short statements
3. Get louder and softer with the music.
4. Know the holes in the piece where a short quick figure may fit well, and hit it hard, and shut up.
Do just like the sax player in Smokie Norful's "I need you now"
