I successfully downloaded a new version of IOS to this 3750 switch, changed the boot system commands, yet the boot variable does not change, nor do the boot statements appear in the running config. I also did a 'wr mem'.
Anyone seen this before?
Enter configuration commands, one per line. End with CNTL/Z.
nhv-c14-sw1(config)#boot system flash:c3750-ipbasek9-mz.122-35.SE5.bin
nhv-c14-sw1(config)#boot system flash:c3750-i9-mz.121-19.EA1c
BOOT path-list : flash:c3750-i9-mz.121-19.EA1c
Config file : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break : no
Manual Boot : no
HELPER path-list :

nhv-c14-sw1#sh run | in boot
I don't have a 3750 to test with and i may be way off base but instead of entering separate "boot system flash.." commands could you just try to enter both images on the same line and separate them with a semicolon eg.
boot system flash:;
I believe you need to have them on the same line and because you are entering them separately it's not ignoring your new IOS it is just overwriting it in the config each time when you enter the second boot system flash string.
