One beautiful book is Peter Schneider's Nonarchimedean Functional Analysis, appeared in the Springer Monographs in Mathematics in 2006. A more analytic one (with less emphasis on Functional Analysis and more on Calculus) in Alain Robert's A course in $p$-adic Analysis, GTM 198. But I still think the bible is S. Bosch, U. Güntzer and R. Remmert's Non-Archimedean AnalysysAnalysis, appeared in the Grundlehren der mathematischen Wissenschaften, 261.
