Most of the subchannels you mentioned are on a fairly strong transponder on the 97W satellite.
If dish size is an issue, there are members here that successfully use small dishes on C band in apartments etc... Danristheman is the resident mini-bud expert over in the FTA section and can answer any questions on what channels you can expect on a smaller C band dish.
