Yes, just get the original firmware file (availalbe on the retail website as an "update" or something, .bin, .trx, whatever.
Tomato(USB) > DD-WRT.
For the use I'm going to give to the router, is it worth it upgrading the firmware to a 3rd party? I mean, the wireless on/off switch is convenient, but I can also do it from the web browser with the factory installed one.

One thing that no one so far has mentioned is that you should make sure your ADSL modem isn't already acting as a NAT router. If it is and you stack another one behind it, you will have two stacked layers of NAT and it may appear to work at first. However, you will have all sorts of problems with anything more complicated than basic web browsing with such a setup. Router functionality in ADSL modems is not uncommon.
If you haven't changed anything yet, the easiest way to tell is to check what IP address your computer gets when directly connected to the modem. If it is any of the following, the modem is doing NAT already:
192.168.*.*
172.16.*.* - 172.31.*.*
10.*.*.*
If you are getting an address in one of those ranges, you will want to either disable the router function in the modem (if you can) when you introduce your wireless router, or configure the wireless router differently.
We will get to the details of that if needed. 
Thanks, I just checked the IP address but the first numbers do not coincide with any of the numbers that you mention, so should I disregard the modem acting as a NAT router?
