...my upload speeds are pretty good at 136 kbps, but my download speeds are maxxing out at only around 300 kbps...
Which operating system are you using? Unless it's Win2K or XP, you very likely will need to "tweak" your RWIN value to realize the full download speed potential. The Dr TCP utility found here on DSLR reports can help with that... I'd suggest an RWIN value of about 32-40K.
