You can assemble the base by your self, but notice that the wheeled feet are not symetrical. Make sure they both face the same way. (not noted in assembly directions) Yes it does take two people to attach the base to the printer mostly to turn the printer upside down, and then to raise the whole thing upright after attaching base.
Yes, the starter carts were a disappointment, but I'm sure they will get you going. The Lt Gray is the first to go, I buy that in the 300 ml size and change out the chipped cap. Also in my experience the Yellow is next to go. If you use the GE a lot, I'm sure that will also be used up quickly. (I don't use it very often)
Happy printing!
