The paper under review is a version of a talk given at the symposium to honour Timothy Trevor West, held at Trinity College on December 19--20, 2005. It contains a collection of problems arising from the work of T.\,T.\thinspace West or related to it. The problems are mainly concerned with the spectrum and the spectral radius in Banach algebras.
