@Aimar -
Just to put in my two cents. I'd use the following:
Corona SDK (use free version)- uses Lua programming language.
Lua Glider IDE (use free version) - works GREAT with Lua/Corona SDK (based on Netbeans).
Codea - allows you to program entirely on the Ipad itself. Uses the Lua programming language.
Textastic - code editor for iPad/iPhone, Objective-C and Lua syntax highlighting, and many other languages.
Texturepacker - download free version
Physicseditor - download free version
You should also set up a free GIThub account, do a short GIT tutorial on youtube (you'll need this as you progress in your development).
Also get a free dropbox account (you'll need it).
Sign up for google docs (and search for project management and game design google docs templates).
You'll still need a Mac, Xcode, and an Apple Developer Account if you want to build to an actual hardware device (and not just use a simulator). So running through some youtube tutorials on Xcode installation, Apple developer registration and setup, and device provisioning (complex) should also be an additional priority.
There is a TON of code and training material on the web for these tools. And many of the tools are the same as those you'd use for Cocos2D development (texturepacker, physicseditor, box2d, etc).
