You can connect any MIDI keyboard to a PC ( including the ones you mentioned ) and just requires the MIDI interface plus software. Cakewalk makes a range of MIDI/digital audio sequencers. The home version of Sonar http://www.zzounds.com/item--CAKHS should be fine and includes a couple of soft synths plus you can add more DXi and VSTi synths as required. M-Audio are well known for their USB MIDI interfaces eg. http://www.zzounds.com/item--MDOUNO

Hope that helps to answer your questions.
