I have a Philips 34PW850H and it's HD ready. I found this page with info

Since it can do 1080i, what happens if I feed it 1080p?

I don't have any digital inputs, HDMI, or DVI. How much resolution can I get out of component cables only?

Can it display 720p well?

It will not accept 1080p at all. 720p should be scaled to 1080i by the TV, but it's possible that it may not accept 720p either. You can get 1080i out of component cables.

This Philips 34PW850H Leaflet (http://www.p4c.philips.com/na4/3/34pw850h/34pw850h_pss_aen.pdf) doesn't mention 720p or 1080p. You can pass full 1080i through component cables.

I found 2 sets of component inputs on the back and only one was labeled 720p/1090i. Even the instruction manual states this and doesn't specify 1080i for the other input. Are both able to go 1080i or is the unlabeled one likely lower?

Perhaps the dual resolution input is there to accept either res (which will be displayed @ 1080i). If that's the case, I'd use it for anything you may have diff resolutions coming from (outboard OTA tuner, maybe?), the other dedicate to a 1080i-constant source (HDDVD/BluRay player).

Or they're the same. Just have to try either res in both. But, you should be feeding it 1080i if possible, at the time.

I would guess that only the component video input labeled 720p/1080i can accept those HD resolutions, and the other (unlabeled) component input will only accept 480i (or possibly 480p).

Component (Y-Pb-Pr) video has been around for some time, and it's not strictly used for high definition signals. I know some standard-definition TVs have component inputs as well. I would guess that your TV has one standard-definition component input and one high-definition component input.
