New Grey Owner: Need some info/advice

Hello all! My name is Kurt and I just became the proud new dad of a 3
1/2 month old Grey. I spent 3 days trying to come up with a name. I
finally settled on Dobie.

Let me give you some background on what I have observed with Dobie so
far... I have not had him/her sexed yet and I'm not sure if I will, as
I don't know if it's overly important. But for the ease of typing, I
will refer to Dobie as a he.

So far, Dobie seems to be adjusting to his new environment rather
well. We also have cockatiel which he does not appear to like at the
moment. Not sure why, possibly due to his new home. According to the
breeder, he was weaned approx a week before I got him. He seems to eat
well and does not appear to have lost any weight based on the simple
scale that I was loaned. He really likes his water softened pellets,
which I am gradually making less soft. I have treated him to some
veggies and fruits which he likes to throw around after chewing on. He
still occasionally does the "baby bird wanting to feed from momma bird
actions". To my surprise, he seems quite social with myself, my wife
and two children. Even though he likes to wrap his beak around a
finger, he doesn't really bite. It seems more like teething. Also,
when sitting on my shoulder, he "preens" my ear much like he would his
feathers. (with the occasional attempt at finding something in my ear)
All told, I think he is well behaved. He even likes to cuddle in a
sense, by burying his head under a chin or in a blanket/towel.
(Sticking his butt right up in the air) I'm sure there is more which I
haven't stated here, but if there is anything I should have provided,
please ask.

Although I have been going over as much info as I can, I still have
some questions which I would like to get 2nd, 3rd and 4th opinions on.

1. At 3 1/2 months, should I be feeding him "baby food" or just
continue with pellets and veggie/fruit treats?

2. How often should he be fed? (currently he gets breakfast, lunch and
dinner)

3. What behaviors should I watch for when feeding that might indicate
he is getting enough, not getting enough or is even at the right stage
to accept certain food items?

4. What is an appropriate and effective method of potty training?

5. What is a safe wood to make a fun and interesting perch/gym for him
to play on?

6. Is it a good idea to play a CD with sounds/phrases that I would
eventually like him to say or mimic? (while we are at work and school)

7. Should his cage be covered when we put him to bed?

8. What are the best and most informative links on the internet for
African Greys?

I know I have more questions, I just can't think of them right now.
Any advice and information would be greatly appreciated. I don't want
to make any mistakes that would cause harm to my new found friend.
