Default I9001 full phone wipe

I have few questions for wiping the phone?

A lot of time passed since I bought this phone, and there are a lot of garbage in sdcard and system itself? I changed many ROMs, and I want to breathe new life to phone.

I am interested in following CWM functions:
format /system
format /cache
format /data
format /sdcard
format /emmc

Will it erase everything and everything from the phone and sdcard, including the system?
Will this remove CWM and Root?
How to flash new system again, when I am not able to boot?

Is above procedure same as this, except that in this case, I am able to boot latest installed system?
- wipe data/factory reset
- wipe cache
- wipe dalvik
- format sdcard
- format emmc

What about code *2767*3855# , what is included under this type of wipe/reset?

Thanks

This just wipes apps. When you format /system it won't boot so you can only install a new ROM or restore a backup.. And no CWM won't be deleted..
Most ROMs format system automatically. But when you upgrade from GB to ICS you should format system and wipe data, cache and Dalvik cache.
And about the code, it's called a hard reset, same as wipe data in CWM.

How to restore backup when I formatted sdcard?

Is it safe to format emmc, and what is purpose of emmc?

Emmc is external SD card, I don't really know if it formats all(music and stuff and apps) or just apps. But i think formatting in CWM wipes apps only ..So better not format it .. no ROM requires formatting SD or emmc
And you should always save backups on your PC..but if you format SD I don't think it will wipe data
