1).For monitors, my personal opinion would be to go for any good 1080p monitors available in your market. Spending a lot on Display is really waste of money unless you're involve in professional editing work's. So pick One which you like most under your budget.
2). Gaming Mouse , there are lot but few options for you: Corsair M65, Razer DA 2013, Logitech G502, Zowie FK2, & the latest Steelseries Riva (My personal options).
3). Corsair vengeance K70 always my favourite (yet), there are some solid keyboard within $100 : Logitech G710+ Mechanical , Razer Black Widow Ultimate, Roccat ISKU.
