1. I only use notepad but EditPad is maybe worth a look.
2. Learn to script from the basics. If you don't understand the scripts you use, you'll never be able to pull off a game with custom scripts.
3. Read the community guide - thats where I learnt everything I needed to write my AGSP scripts.
4. I am very blunt now, but if you don't know or don't care to use punctuation in your posts, you'll be having a hard time writing even a single script line. Maybe you should start at the VERY basics.
In case you find my grammar and spelling weird ---> native German speaker ^^
