Seems like it still exists, because IE8 is the shipped browser on Windows 7.

All IE requests go through Wininet. Have a look at the Win7 SDK header files:

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include>findstr /spin /c:"INTERNET_MAX" *.h
WinInet.h:85:#define INTERNET_MAX_HOST_NAME_LENGTH   256
WinInet.h:86:#define INTERNET_MAX_USER_NAME_LENGTH   128
WinInet.h:87:#define INTERNET_MAX_PASSWORD_LENGTH    128
WinInet.h:88:#define INTERNET_MAX_PORT_NUMBER_LENGTH 5           // INTERNET_PORT is unsigned short
WinInet.h:89:#define INTERNET_MAX_PORT_NUMBER_VALUE  65535       // maximum unsigned short value
WinInet.h:90:#define INTERNET_MAX_PATH_LENGTH        2048
WinInet.h:91:#define INTERNET_MAX_SCHEME_LENGTH      32          // longest protocol name length
WinInet.h:92:#define INTERNET_MAX_URL_LENGTH         (INTERNET_MAX_SCHEME_LENGTH \
WinInet.h:94:                                        + INTERNET_MAX_PATH_LENGTH)
WinInet.h:1712:#define MAX_GOPHER_HOST_NAME        INTERNET_MAX_HOST_NAME_LENGTH
WinInet.h:1720:                                    + INTERNET_MAX_PORT_NUMBER_LENGTH   \
Winineti.h:1511:#define URL_LIMIT INTERNET_MAX_URL_LENGTH

So, yes, that length limitation applies.

Yes, according to Microsoft.

The length limit for IE7 and IE8 is currently 2083 characters.

If you think you are going to go over this limit, you can use a a frame with a short url and contain the page with the long url inside that frame.

According to this knowledge base article it applies to IE7 and IE8:

I have Javascript successfully executing a GET request successfully up to to 4096 characters in Internet Explorer 8. Requests longer than this will execute, but the parameters beyond that length are truncated off. I can't find that documented anywhere, but that's what I've found empirically.
