Cyclone IV FPGA (EP4CE10E22) circuit

Hi,

I am making a circuit based on Cyclone IV FPGA (EP4CE10E22).

1)

Is it possible to find schemes for JTAG interfacing?

2) Does this FPGA have an internal configuration memory? If an external memory is to be inserted, which is recommended and a reference scheme exists?

3) The package type is a E144. It is equivalent to QFP144?
