Need help on filter and hood question

Hey everyone. SO I apologize for asking but after searching threads, I found no answer. I have a T1i and while finances keep me from getting what I really want (I'm sure we all suffer from this!) , I am having to get the basics to get going with the 18-55 kit lens. First thing I was wanting to get was a lens hood. My understanding is since the end element on the kit lens rotates it will cause vignetting at the wide angle, so the hood is a round hood and not a flower type hood. Here is my question. I am wanting to get some filters like a uv and definately a circular polarizer. However, since this type of filter screws into end of lens and the element twists as camera focus, how do you use this type of filter with such a filter? Question #2 is if it's possible to get access to the filter and put the lens cap off/on if the hood is in place. I realize it sounds silly, but without seeing it, I have no way of knowing and am hoping someone here can shed some light on this.
Many thanks!!

#1. Don't get a UV/Protection filter for such a cheap lens

#2. To use a polarizing filter, adjust the polarizer strength(rotate) after focusing

Circular Polarizers pose challenges on lenses whose front element rotates. You have to play with it a lot to get the effect you want.

As to lens caps, I swapped out my caps for center pinch caps like you see on Tamrons. In fact Tamrons are my favorite caps.

You will probably need to take your hood off to take your filter off or put it on.

I only use UV filters when they have a true protective function. On my 24-105 on my 7D at the beach for instance. Otherwise I'm of the no filter camp.

Well, the rotating front end won't affect a UV filter, although you're understanding correctly that it would a petal hood or a polarizer. For more on protective/UV filters, see here. I have B+W MRC UV filters on all my lenses that accept them. They only come off if they need to.

Even with a rotating front element, you can use a circular polarizer. Just make sure you've at least rough-focused on your subject before you try to adjust the polarizer for maximum effect. If you're close to the correct focus the small amount of rotation you'll experience won't change the effect very much. Just make very sure you don't get a linear polarizer; they'll behave inconsistently with the partially-reflective mirror used in your autofocus system.

Canon's lens caps aren't the easiest things to use with a hood in place. I've replaced all my lens caps with Tamron's. The center pinch points make it possible to remove it with a hood on the lens.

You are correct, since the front element rotates, the proper hood is not petal shaped. The Canon hood, EW-60C, is a hard plastic bayonet mount hood. The hood reverse mounts to save space when stored.

Adjusting the CP with the Canon hood in place is extremely difficult if not impossible. Fortunately, the hood can removed with a quarter twist, but that leaves you without the advantages of the hood. You might want to consider one of the collapsible rubber hoods that screw mount to the lens. When collapsed, some of them provide easy access to a CP.

To Use the CP you must first focus, then hold the focus ring while you manipulate the CP filter. The focus ring, as you are no doubt aware, is very narrow so this can be difficult to do without disturbing the focus. The Canon lens cap can can be easily attached or removed with the hood in place.

I'm not sure I would call it that bad to use a CPL with a hood. I use one with my 17-55mm and hood.
