I am looking for a basic book about Topology (maybe also a bit of Functional analysis but basically Topology) including the following points (in addition to the basic points):
$\bullet$ Seminorms
$\bullet$ Locally convex topological vector spaces
$\bullet$ weak-$^{*}$ topology
Check out http://www.math.uwaterloo.ca/~lwmarcou/Preprints/LinearAnalysis.pdf
This was the book used for my functional analysis course. It is a functional text more than a topology text book, but has chapters on those 3 bullets you listed and other related topics. I liked it very much.
