You pretty much have to buy Weatherlink to get the Data logger connector.
To be fair this isn't just a bit of wire and connector- it can store (up to) several weeks of data which can be downloaded at intervals should you not want to keep it connected to a computer permanently.
I found Weatherlink capable but decidedly clunky and old fashioned, the main contemders for alternative software which can do all the logging and at least some of your sums are Weather-Display and Cumulus.
Both have their good and bad points. Cumulus seems generally easier to set up but WD has an immense amount of customisation options you can tinker with later.
Bear in mind that you can only easily run one software dealing with the data at a time, so a decision needs to be made quite early on which one works best.
You could use weatherlink initially, and import the logfiles to most other software at a later date if desired.
If you buy weatherlink just for the data logger, there's no pressing need to install the actual software at all, but you do need drivers so the computer can communicate withe logger and console - either from the supplied disc or download from the Davis site.
The radio link is rock solid with the Vue, it is practically the same system as used with the VP2, in fact the consoles are interchangeable.
