If it is primarily HT, I would definitely go with bookshelf/monitors. Since you need Sub-woofers for HT anyway, why pay for redundant capability in your floostanders that you will be crossing over to sub-woofers anyway? Not only that, but you can usually get a higher quality bookshelf/monitor since the designer can concentrate his/her efforts and material expense on the mids and highs -- and you'll get higher quality lows because it costs $$$$ to get floorstanders that do bass well. I'd rather have a higher end bookshelf/monitor than a mediocre floorstander. Again -- why do that if you're just going to cross the bass over to the sub-woofer anyway? You can save that money, eliminate the redundancy, and end up with a better system by going with bookshelf/monitors and sub-woofers. But, don't skimp on the sub-woofers.
