#1 - The only way to create a rounded corner, is by using images.
#2 - You would in fact have to create an image map, however, it would have to be created under "LASTN_WEBSITE", and you'll have to use div layering to position it to where you wanted it so show up.
#3 - If you have a paid account, you can embed your livejournal.

While logged in, go to
http://www.livejournal.com/modify.bml and scroll down until you see "Domain Aliasing." Enter your domain name in the text box. For this to work, you'll need to arrange to have your domain name's DNS point to LiveJournal's IP address, which is 66.150.15.150. If you do not have the ability to change this yourself, your web hosting company should be able to make this change for you.
LiveJournal does not provide DNS services. You will need to obtain DNS services from your web hosting company or your domain registrar. Setting up your domain's DNS typically contains two parts. First, you must specify two DNS servers (an "NS record") and then you must specify what IP address these point at (an "A record"). Different domain registrars will provide you with different levels of control over these options. Typically, you will not need to change the NS record at all, but need to change the A record as explained above.
Since LiveJournal does not offer a DNS service, it is not possible to use this feature if your domain registrar only allows you to control your NS records, or does not allow you access to DNS records at all. If you are unsure of how to make the required changes or do not know if your registrar offers you the ability, you will need to contact them, explaining that you wish to have your domain's A record point to 66.150.15.150.
If you are familiar with DNS and how it works, you could also set up a CNAME record pointing to livejournal.com, rather than an A record pointing to 66.150.15.150.

If you do not currently have a domain registered, Domain Monger (http://www.domainmonger.com/) allows you to register domains fairly inexpensively. If you use Domain Monger, you will be supporting LiveJournal, as LiveJournal receives a small referral fee from Domain Monger. However, LiveJournal does not require that Domain Monger be used. Instructions for setting up a domain registered with Domain Monger are below. If you use a different site to register your domain, their technical support staff should be able to set up the alias for you.
