Ever heard of the 7 Mounting Heavens of Celestia? Anyone ever heard of Valmar? Its essentially a giant rock in the middle of a huge ocean, that has a mountain as its primary feature with different levels for the different Valar.

The idea of "seven heavens" hardly originated with Tolkein. As for the "giant rock in the middle of a huge ocean" etc., that 1) doesn't sound familiar to anything in D&D (at least from the Gygax era) and, 2) does sound awfully similar to Dante's Purgatorio. So I'm not sure what it is you're getting at.
Balrogs, ents, wargs, and hobbits are all acknowledged borrowings from Tolkein -- which is why D&D no longer has creatures with those names -- they were changed to Type VI Demon (Balor), treants, worgs, and halflings respectively. Direct Tolkein references were also stripped out of the descriptions of orcs (to specific tribe names -- Red Eye, Mordor, White Hand, Isengarders, etc.), wights (to barrow wights), wraiths and spectres (to Nazgul), red dragons (to Smaug), and rocs (to Tolkein's eagles). Furthermore, while no direct reference was made in the descriptions, the ranger class and werebear (Beorn) are also clearly derived from Tolkein. Nobody is denying any of this (at least nobody who's actually seen an early-printing copy of
Chainmail or OD&D). The points of contention are how much of Tolkein vs. other sources is in D&D's elves and dwarfs, and whether or not all this stuff was merely thrown in as a sop to Tolkein fans in a game that was (per Gygax's later claims) more proximately inspired by Howard, Leiber, Vance, Burroughs, Merritt, Anderson, de Camp & Pratt, and Lovecraft.
