Hacked > changed password > Error establishing a database connection Parse err

Think these are probably separate problems, but am not sure…

I changed my password on recommendation of my provider, because
my site has been hacked resulting in (amongst other things, I assume):
– a google “warning: visiting this site may harm your computer” message.

When ignoring those messages, the next barrier is:
– 1 site: Parse error: syntax error, unexpected ‘)’ in /home/xxx/11je.com/indiaaa/wp-config.php on line 97.
(I checked all info in wp-config.php, which seems to be fine, is there anywhere else where I can find this info, for comparison?).
– 2 of my sites having an: Error establishing a database connection.
(I checked all info in wp-config.php, which seems to be fine as well).

Lastly, I cannot access any of my log-in pages (which worries me the most), but have access to FTP.

Please note that all of this is “fairly new” to me (as long as things go well, it is all very easy…). The idea of pasting lines of code, etc. freak me out. Please, if you can, give a “step-by-step” or a “for dummies” solution. Thank you very much in advance.
