Hi @Joey Arata,
It seems everyone has already covered most of the basics, and at the end of the day it will be up to you to learn the subtle nuances of landlording (some, unfortunately, by trial and error). That being said you should still strive to work smarter instead of harder, so I thought I could provide you with a few useful online tools to get you started in the right direction.
1) www.mapliv.com is a nifty tool that can give you a solid idea of how much money your property could bring in each month. Essentially it scrapes craigslist listings and puts them on a map of the area surrounding your property. It sorts them out based on size, price, and location in regards to your property. It is a great place to start, but should not be the sole tool used to set your rent rate because it neglects interior upgrades, size of the lot, etc. I'd recommend starting with it to get an idea, then cross checking by identifying the quality of other properties (meaning interior upgrades and proximity to transportation/shopping centers) by viewing the actual listings and pictures. Keep in mind that it is not uncommon to adjust the rent rate based on the amount of interest you receive, so don't be afraid to adjust it once the listing is posted.
2) postlets.com is a great way to blast your listing out to over a dozen different listing sites, including craigslist, trulia, zilllow, and hotpads. You make one, uniform listing and it will be on the other sites usually within 24 hours of completing it.
3) tenantify.com is a popular tenant screening service, charging only $15.00 for a background and income check. That being said there are a ton of these services online so I would recommend researching them yourself to see which fits your needs the best. When doing this check to see if they are instant services providing soft background/credit checks, or if they are providing more thorough hard checks like iscscreening.com.
4) Here is a link to the national Fair Housing Laws, which I strongly recommend familiarizing yourself with. Not knowing little details such as the illegality of discriminating against an applicant's source of income can lead to big problems down the road.
I hope these tools are as useful to you as they have been for me in the past.
Good Luck!
