Hi klacey, and welcome to the forums.
All of the points that you've mentioned are the result of the incomplete status of the game; you've asked about features that haven't been implemented - yet.
As these features have not been implemented yet, it is therefore currently impossible to create taskforces or invade systems. The game also lacks an AI (Artificial Intelligence), so the other empires and minor races was literally sit there and do nothing - they won't even build food buildings to feed their populations because they essentially can't think - yet.
The AI will likely be one of the most complex parts of the game to implement, and as such will be one of the last parts of the game that will be finalised. That said, we *may* have an early version of the AI in the game within a few months, depending on how quickly Mike (The developer) can implement it. It will require a lot of tweaking to get it working as we want it to though; this will require feedback from people who test it, or we could end up with Klingons that run from combat and the Federation acting more like the Terran Empire.
As for invasions and fleet creation, i'm not sure how long that will take to implement, but I imagine it will be easier than implementing an AI. Other than that I can't say how long it may take to implement, i'm sorry. It will definitely be in the game one day though.
