Spreading Seas does not change the name of the card. It does change the card's land type. So the enchanted Urza's Mine now has the subtype Island instead of the subtype Urza's Mine.
My question is do the other two Urza's Lands tap for 1 mana or more than that? Do Urza's Lands care about the name of the card or the subtype?
They care about the subtype, so they'll just tap for 1. "Urza's", "Tower", "Mine", and "Power-Plant" are all land types, and that's what their abilities look for.
If they were looking for the name, they would say "if you control a land named {} and a land named {}, ..."

Procrastination is an art form, and I am an artist. Knowledge knows no bounds.
And so people say to me, "How do I know if a word is real?" You know, anyone who's read a children's book knows that love makes things real. If you love a word, use it! That makes it real. Being in the dictionary is an artificial distinction; it doesn't make the word any more real than any other word. If you love a word, it becomes real.

So they will, in fact, tap for the default "1" colorless. This is why Evil Presence, Spreading Seas, and Blood Moon work so well against Tron
