I have yet to run out of room in my bag in any of the new Pokemon games. Items in your bag only go up to 99 though so If you wanted 198 Proteins you'd need 99 proteins and another 99 proteins.
You get money by fighting trainers (Pretty much anywhere - even standing in water!), or you can sell some of the stuff you find on the ground THAT ISN'T NEEDED.
The system will only hold a maximum of 3 wonder cards. You might want to use it as much as possible before deleting it, though. Pokemon Diamond and Pearl also hold a maximum of 3 wonder cards, too.

Google Pokemon diamon glitches sorry im not much help
Not much. Pokemon diamond and Pokemon pearl have different Pokemon. for example, in pearl you can catch a glameow but not a cranidos and in diamond you can catch a cranidos but not a gleameow. And at the end of pearl you can catch Palkia the legendary and at the end of Diamond you can catch Diagla. But the games are basically the same. And there you go.....
Yes, much like it's predecesores (Ex. Pokemon Gold and Silver could trade to Crystal) Pokemon Platinum will be able to trade Pokemon from Pearl and Diamond.
First, you find a Pokemon you don't have. Then you weaken it with attacks. Then, you spam pokeballs until you catch. Repeat until you have so much Pokemon.
