Fractured T3 at college

You read the title: beging tweaking. I have been registered for a while, but have been on dialup until a week ago, so had no need to tweak.
My sea.speakeasy.net results are:
"2002-09-06 23:06:20 EST: 6382 / 3348
Your download speed : 6382489 bps, or 6382 kbps.
A 779.1 KB/sec transfer rate.
Your upload speed : 3348214 bps, or 3348 kbps.
Seems like broadband .. above the 1mbit barrier!"
which changes quite a bit however, but the highest i have gotten is around 7200 for down, and 6800 for the up.
My tcp/ip analyizer goes as follows - and i know by reading this that i have to change some things, but don't want to screw things up. - i have tcp/ip optimizer and cablenut freshly installed:
"Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
Note: Read the FAQ if the above is not your IP address.
TCP options string = 020405640101010101010402
MTU = 1420
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1380
Maximum useful data in each packet = 1380, which equals MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 1460
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 1460
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
507840 (MSS x 46 * scale factor of 8)
253920 (MSS x 46 * scale factor of 4)
126960 (MSS x 46 * scale factor of 2)
63480 (MSS x 46)
bandwidth * delay product:
Your RcvWindow limits you to: 58.4 kbps (7.3 KBytes/s) @ 200ms
Your RcvWindow limits you to: 23.36 kbps (2.92 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 50 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000"
