in my opinion it's not worth obsessing over free space, especially storage. Why do you really need the space? Ram I can understand, but storage? Nah. Wouldn't you just want your phone to run as quickly and as smoothly as possible? Isn't that the goal?
Don't forget to take into consideration that the link to the rom you posted doesn't have google maps or opera cooked in, so if you use those programs, you'll need to load them yourself and decrease the available memory.........
