Apologies for the delayed reply. Glad your import worked OK. I use a NAS which also works fine over wireless but have used an external drive in the past.

In the Audio view on the left hand pane you have the option to view by Albums, Artists, Files etc. Albums lists them all in alpha order of album title but if you choose Artists you can click on artist, click on album and double click the first track shown in the lower pane. The album will play through. In Album view, double click the album and then the first track. In Files view you can sort by album and double click the first track of an album and it will keep playing through to the bottom of the list!
