Well from that, Jesus was obviously more focused on Kingdom and heaven rather than hell.  Let's see what the Apostles had to say:

Hell

James 3:6; Revelation 1:18; Revelation 6:8; Revelation 20:13; Revelation 20:14

Hmm, strangely few verses.

Heaven? (esp. references to Heaven as where God is)

Acts 3:21; Acts 4:12; Acts 7:49; Acts 7:55-56; Acts 10:11-12; Acts 11:9-10; Acts 17:24; Romans 10:6; 1 Corinthians 15:47; 2 Corinthians 5:2; Ephesians 1:10; Ephesians 3:15; Ephesians 6:9; Philippians 3:20; Colossians 1:5; Colossians 1:20; Colossians 4:1; 1 Thessalonians 1:10; 1 Thessalonians 4:16; 2 Thessalonians 1:7; Hebrews 8:1; Hebrews 9:24; Hebrews 10:34; Hebrews 12:23; Hebrews 12:25; 1 Peter 1:4; 1 Peter 1:12; 1 Peter 3:22; 2 Peter 1:18; Revelation 3:12; Revelation 4:1; Revelation 4:2; Revelation 5:3; Revelation 5:13; Revelation 8:1; Revelation 10:4; Revelation 10:8; Revelation 11:12; Revelation 11:13; Revelation 11:15; Revelation 11:19; Revelation 12:7-8; Revelation 12:10; Revelation 14:2; Revelation 14:13; Revelation 14:17; Revelation 15:5; Revelation 16:11; Revelation 18:1; Revelation 18:4; Revelation 18:5; Revelation 18:20; Revelation 19:1; Revelation 19:11; Revelation 19:14; Revelation 20:1; Revelation 21:2; Revelation 21:3; Revelation 21:10
