Dear Salija, convolutional encoders are hard to check by hand. Typically, you'd try to decode to verify. PCCCs can be made systematic, I'm not sure that's the case for the GNU Radio implementation.
Regarding the interleaver: turbocodes rely on adding redundancy calculated from the input data stream, and an permutated version of that. That permutation is done by the interleaver. Without the interleaver, you'd just have two times the same information added as redundancy, and that wouldn't really be an advantage over just using a simple convolutional code that adds twice the redundancy.
