Yes PuTTY is a must have, also another screenshot tool to add is GreenShot. Sysinternals is a must, as well as several of the nirsoft tools (fast resolver, netresview, bulletpass) http://www.nirsoft.net/. Also having your boot cds I usually use parted magic, hirens, konboot and PLOP Boot Manager are a few in my kit besides install disks for XP , 7, debian and ubuntu. Also I'd be lost without Keepass Just my 2 cents
