Hyperactive Dog, Cant Train Him, Could Have Mental Issues?

i rescued and adopted a dog 4 months back, first he had seperation anxiety then he got over it, but he is just toooooo hyperactive, never gets tired, he plays with his rubber ball all by himself, takes it tosses in the air then catches it. He will be on the couch playing with the ball and it will fall on the floor 100times and 100times he will pick it up and make it fall the same way.
When i want to take him out for a walk as soon as he sees me taking the leash he gets so excited, so hyperactive he starts making these squeeking noises and just goes crazy. he doesnt listen to me, when he is on a leash he pulls like crazy and keeps going left and right, sometimes he has accidents in the house even though he knows where he has to go.
if i am walking him and he sees a child he goes crazy and starts barking like mad. when i come home from work my other dog greets me normally, wagging her tail and all happy but he, he goes jumping in my mouth, jumping alll over me, trying to knock me over, just jumping like mad.
i want to calm him down, train him but its impossible, cant afford a trainer atm but id like to know what i can do to calm him down (no medications) and why is he acting like this, is it normal or is there some mental issues?my other dog does not act like this at all. he is a very loving dog and i love him to bits but id like to calm him down especially when ppl come over.
btw he is a papillon, about 1.7yrs old

Could Someone Give Me Some Housebreaking Tips For A Papillon?

I got my papillon puppy yesterday and so far everything’s been great. She has a wonderful temperament, is extremely intelligent and playful and is simply a perfect bundle of fur. Of course, as with all young puppies, my little Lilou needs to be housebroken. I know I’ve not had her for very long so I can’t expect too much, but I’d like to start off on the right foot (or paw, =P) so things don’t become a disaster later on.
I’m crate training her, and so far she’s been fantastic. She hasn’t soiled her bedding yet, even when I feared she wouldn’t make it through last night. However, I’m still having some small problems with the housebreaking process, especially with predicting when she needs to go.
Many books and various websites recommend to take a puppy out to the toilet /immediately/ after they’ve eaten, after they’ve woken up in their crate, after playing, after exercising, before they go to bed… etc. And the key word is /immediately/. Lilou doesn’t eliminate immediately; she doesn’t eliminate five minutes later; she doesn’t eliminate ten minutes later; she doesn’t eliminate fifteen minutes later, and all this means that taking her out immediately has no effect. I can’t predict when she will eliminate, and it’s not possible for me to hover over her twenty-four seven. She’s about ten weeks old, so does anyone know (or at least have a vague idea) how often I /should/ take her out rather than immediately after everything?
Also when I do take Lilou out, she gets distracted. Okay, sure, many puppies get distracted, but how do I fix this? She loves to play and every time I take her to the grass area where I want her to do her business, she runs off and goes to chew grass. I can’t get her to stand still and I wait for an eternity, outside, for nothing. Last night I was outside with her for a full two and a half hours until half past eleven when I gave up and put her in her crate. She eliminated this morning at six. While that was lucky, that won’t be the case during the daytime when she’s taking three meals a day with water always available.
I know I might sound to some of you that I’m expecting my puppy to be perfect, but I’m telling you right now that I’m not. I just want to know if I’m doing anything wrong so I can fix it early and therefore train my puppy better.
Any tips and suggestions would greatly be appreciated.
