Can trapdoor spiders kill a human?
Humans very rarely get bitten by members of most species of spiders that have trapdoor to close their burrow entrances. So it is impossible to tell how toxic the bites of some trapdoor spiders might be. There is one kind of dangerous spider in Australia that builds burrows and closes them off with a trapdoor. They belong to the genus Hadronyche. They are similar to another kind of funnel web spider that does not make a trapdoor, Atrax. In a quarter of all cases of reported bites there were severe consequences. There have only been 64 cases in the past 23 years. Nobody has died of these bites since antevenom was developed.
There are other trapdoor spiders whose bites are not regarded as medical problems. The fangs are big enough to make their bites painful the same way sticking yourself with a darning needle would be painful, but the venom does not bother humans very much.
In between these extremes there will be cases where a spider that is capable of giving a medically significant bite does not inject enough venom into the wound to cause big problems, and there will also be species that have venoms of intermediate toxicity.
These spiders generally have poor vision and depend on vibrations that they sense through their legs. So it is possible to get bitten simply by lightly touching the ground near a burrow. People who keep these spiders for study have to be careful not to put their hands into their cages to remove dead insects, put water into their little bowls, etc.
Unless you live in Australia it is highly unlikely that you will ever get a serious bite, but people should always respect spiders. It is rare for spiders even to be belligerent guards of their territories, so there is little reason to expect that a trapdoor spider might "come after you." On the other hand, if a human forces himself or herself on the spider's attention by causing it fear and/or pain, then the human is just asking to get a defensive bite. Since we don't know for sure which of these very shy creatures might have some unusual toxin that could be a big problem for us, it is better to avoid doing anything that could get the spider to bite.
How dangerous is a wolf spider?
Wolf spiders are not as dangerous as you think. Even though a wolf spider's bite is poisonous, the venom is not lethal. Wolf spiders aren't know to be aggressive, but they will bite if thy feel threatened or in danger.
However, if you are bitten by a wolf spider, you should still see a doctor immediately. You should also, instead of a bandage, use an ice pack on the bitten area until the swelling goes down. If necessary, try to avoid any movement at all were the bitten area is. And another important thing is to also call an exterminator to make sure you don't see any of those little guys again!
What parts of the body are removable?
Only the appendix has no known function. I believe astronauts have it removed before going into space.
There are other parts you can manage without if they are adversely affecting your health.
Tonsils and adenoids were removed frequently 30-40 years ago but this is less common now. You can manage with only one kidney. If the spleen is seriously damaged it can be removed but this affects the immune system.

Do spiders come in your room if you have a hamster?
Hamsters aren't known to be particularly aggressive creatures, so it's very likely that spiders will continue to come into your room even if you buy a hamster in an attempt to ward them off.
If spiders didn't come in your room before you had a hamster, it's unlikely that the presence of a hamster would increase the frequency with which spiders enter said room.
