The EZ Recovery app lets you flash recovery ROMs: TWRP or CWM

That is a part of the ROM you can boot into to perform low-level functions such as clear cache, format, factory reset, create/restore NANDroid backups. Think of it like booting into Windows Recovery Disc.

I'm pretty sure (but haven't confirmed yet) that the Dalvik cache is on the /cache partition, so clearing/formatting /cache will also wipe Dalvik

CWM is a recovery ROM; there's no need to install another recovery unless you wish to change it to a different one.
Use CWM (or whichever recovery) to create a NANDroid backup (preferably to an external SD card if you have one installed). These are great for when something goes wrong or for whatever reason, your phone is borked, you can wipe and revert to a known good backup from recovery or from switching between custom ROMs.
