Is the UPS a battery powered UPS, or is it just a power strip? If the UPS is battery powered, you should be fine, the neutral (common) buss is grounded at the source (house panel, somewhere) so the UPS will ground as it needs to. If it's just a power strip, you'll maybe run into issues. Ground wires are designed to be non-current carrying conductors, they are there for 'extra' stuff accumulated in the house. Static electricity, radio frequencies etc, basically a bunch of electrical noise that's best gotten rid of back to the panel. The other 2 conductors (240v is 2 'hots', 120v is 1 hot/common) are both current carrying, depending on what's in the line you can get 'shocked' from either. An ungrounded system leaves no room for accidents...

An ungrounded system leaves no room for accidents. Bad voltage, spikes, static all have no room to leave, no ground. Touching the frame, you make the ground, so you become the path, you get shocked, the frame gets electrically charged and anything attached to the case gets spiked in reverse, the electrical discharge 'goes in the back door' so to speak. This is bad. It's a worst case scenario, but generally speaking, an ungrounded piece of electronic hardware, be it a TV, radio, pc etc is just an expensive accident waiting to happen.

If you don't have a battery powered UPS, I strongly recommend that you get one, sooner rather than later.

Yes, it has a battery. In a ups like yours, power charges the battery, the battery powers the pc. If the power goes out, the battery beeps to let you know that you have a short time to save and close any important files. This is a good thing. The battery should be monitored occasionally, and they'll usually last about 2 years, before you need to replace it (the actual battery inside, not the whole UPS)

1. Never, ever try and clean a pc when it is power on. Ever.
2. Static electricity is a difference in potentials, and your body creates it just by moving. If the pc has a grounding pathway, then when you touch the case, the static on you travels from you to the case, or vice versa. That's the shock you feel. If you unplug the power from the back of the psu, you eliminate the grounding pathway. So when you do touch the case, the static equalizes between you and the case, so becomes safe to touch components. When working on a pc, its advised to unplug everything, put the pc on a piece of cardboard on a table and wear shoes..
3. Yes. You will get 'noise' from the pc, it can't be helped. Powered pc speakers are especially vulnerable to this as the power connector has no ground either. You can try and minimize the noise by having the power come from the wall for that power connector, but with cheap pc speakers that are mainly unshielded and ungrounded, you'll get the buzz.
