Version 3 has different dyes and, like v.2 a different forumlation
concerning dNTPs and ddNTPs.

As far as I have heard: Yes.

Have not tried it, but was told by support, that v3 and v2 enable to
read longer sequences than v1 due to forumlation (see above). This may
result in weaker signals for the smaller fragments.

Hope I could help,
have a nice weekend,
