Greetings, fellow traveller.
You get Eschew Materials for free as sorc, which is good, because your spell component pouch fuses with your new body, when casting fotd I/II.
Since dragons can usually talk - and you have draconic as language as well, I'd rule, that yes, you can still cast spells while in dragon form.
Similar goes for elemental body - maybe you should pick up the specific language as well to be on the save side.
Ruyan.
