Aegaeus recommended plugins? are these suggested?

Can you suggest what plugins are recommended for the Aegaeus theme? these appeared in my wordpress plugin dashboard, unsure if I should activate or not: akismet, gravatar widget, jetpack, hello dolly, polldaddy, pushpress, wp supercache, wp smush.it.
one other question re plugin: do you suggest a plugin to create a colorful tag cloud? thank you kindly!
