If that's *ALL* you're using the internal network for, then 10Mbps is more

Correct, at least assuming you're using a hub. If you're only connecting
two computers, a crossover cable does the job for less money, and may
produce better speed. Given the relative prices, I don't recommend buying
a 10Mbps-only NIC for most purposes; 10/100 NICs go for $25 or $30, even
at local retailers like CompUSA, and you can get them for under $20 from
mail-order outfits. You can shave $5 or $10 off that for a 10Mbps-only
device, but IMHO the savings isn't worth it, since you may well want to
upgrade in the future, and that'll cost you more money and require you to
monkey with drivers and whatnot. Hubs may be another matter, but I've not
checked hub prices lately.

Again, if that's the ONLY thing, you'd need something over 10Mbps to chew
up over 10Mbps of bandwidth.

1 byte = 8 bits
b = bit
B = byte
1KB = 1024 bytes
1Kb = 1024 bits (or sometimes 1000 bits)
1MB = 1,048,576 bytes
1Mb = 1,048,576 bits (or sometimes 1,000,000 bits)
Your analog modem is 56Kbps, or 0.056Mbps, or 0.56% of the 10Mbps NIC's
capacity -- note that's POINT five-six, as in roughly half a percent.
(This is all fudging a bit because of issues like full vs. half duplex,
compression, etc., but those factors won't come near to changing any
decisions you might make about your home network based on the relative
speeds of these devices.)
Now, as I've implied already, there are other purposes for a home network
besides IP masquerading a PPP connection (what I assume you're doing with
this). If you want to do file sharing, printer sharing, telnet, or
anything else on your internal network, the internal network's speed
becomes important for those factors. For these functions (well, maybe not
telnet), a 100Mbps network is better than a 10Mbps network -- maybe not
by a factor of 10, but by a substantial margin.
