https://ammorack.wordpress.com/ <--- not bad
http://www.thearmoredpatrol.com <------ my prefered WG news aggregate/blog
https://vk.com/wotclue <------ Russian FB WOT site. pretty interesting stuff since they get press releases we don't in the West
http://www.vbaddict.net/wot.php (dont forget to use the ADU!)
http://www.tanknumbers.com/en/index.php some really in depth info if you want to dig for it. the site is clunky but it works and there's some really nice stuff in there.
http://www.wotinfo.net/en mostly camo but has other stuff too.
http://na.wotzilla.com <---- awesome site
http://wotnumbers.com/ <--- Wotnumbers.exe. good local program if you don't want mods or net based.
http://forum.worldoftanks.eu/index.php?/topic/185348-09201-wot-replay-analyzer-wip-2-30102017/ <---- ReplayAnalyzer.exe also a good program but requires every replay to be saved seperately. (all instead of Last battle)
