Does a sorcerer multiclassing into a prestige class that advances his spellcasting keep getting bloodline powers? How about bonus spells known?
Does a wizard multiclassing into a prestige class that advances his spellcasting keep getting arcane school powers? How about bonus spell slots?
As per RAW of prestige classes:
Spells per Day: At the indicated levels, a dragon disciple gains new spells per day as if he had also gained a level in an arcane spellcasting class he belonged to before adding the prestige class. He does not, however, gain other benefits a character of that class would have gained, except for additional spells per day, spells known (if he is a spontaneous spellcaster), and an increased effective level of spellcasting. If a character had more than one arcane spellcasting class before becoming a dragon disciple, he must decide to which class he adds the new level for purposes of determining spells per day.
I would say bloodline powers, no. Spells per day and known, yes

The rules are pretty clear to mee, too. You get additional spells known (including the 2 bonus spells per level as wizard), spells per day and caster level. You do NOT advance in school powers, bloodline powers or other class features of the base class (so your familiar won't keep progressing anything besides his hit points). You gain no new powers and the powers you already have don't get better.
The one thing I'm not 100% sure about are the bloodline spells. Personally, I think they belong to "spells known" so a sorc should get them even if he takes a prestige class.
I like to think that they get the bloodline spells regardless of prestige class.

Reading the Bloodline descriptions, every thing your bloodline is giving you only comes from your sorcerer levels. So no bonus spells.

So, not so clear after all, eh?

Considering they're specifically listed on the sorcerer table, I think no bonus spells know seems much more likely to me.
Specialist wizard bonus spell slots I'm not so sure about. On one hand, they're analogous in concept to bloodline spells known. On the other, they're arguably not an separate abilities gained as you gain wizard levels, but all a property of the school specialization: the way it's phrased is "you get another slot of each spell level" (as opposed to "you get a 1st-level slot at Wiz1, a 2nd-level slot at Wiz3" &c.)
