Hard no to both.
Achievements already exist in the form of FW promotions, Activity Tracker, and player-made medals (which is a very poorly implemented feature that is also underutilized probably due to poor implementation and uselessness and waste of 5m ISK). The game does not need other forms of achievements: this is not interesting, does not enhance the game experience (not even RP-wise), and expends precious CCP manpower that could be used on other things. Admittedly, FW medals could be displayed in the Character decorations tab alongside player medals, but that’s really about it.
And we don’t need aliases other than the ability to name a Ship whatever you want - that makes things confusing (actual name + ship name + alias???) and spams the display + overview with unnecessary information (it would be a never-used column for starters).
