I wasn't a huge fan of LiteIDE when I tried it. I prefer GoSublime[1] with SublimeCodeIntel[2], with goimports[3] for my gofmt command. The combo of the three is really awesome.
What does SublimeCodeIntel provide that GoSublime doesn't already give you? GoSublime gives you Gocode support, so you have full auto-complete already.
