They can become beasts at Deceive etc.
what powers and rituals recommend to start
for rituals what the Gm allow. Rule of thumb pick int bonus for you. 1-2 type of summoning lesser, beast/mount, bind, bond and after it other what you find interesting.
Agreed on the Magister Immaterial. If you want to be a support/buff/crippler in battles and good at social stuff, focus on telepathy and Tzeench powers.
You have the advantage that you can use unfettered powers without (too much) risk, but should avoid pushing - as an unbound psyker, you cause a bigger ka-boom but trigger perils more than a bound psyker, and whilst you're immune to psychic phenomena, you've little protection from bad perils of the warp (kind of the reverse of the thousand sons sorceror).
A lot of telepathy/tzeench powers can cause distractions, stunning, give other players openings (Compel - "drop your sword" or "stand up" is a perfectly valid command, and a lot easier than "stab yourself to death"), and learning to use them more subtly helps in non-combat situations, too. I think Mantle of Lies is quite a good one.
