Question? Creating a website that has 2 sets of intermidate tables

I am creating a web site that uses 6 tables from one database in mysql (example)

2 sets of tables that connect to intermediate tables (using foreign keys to join the tables).

1) Category -> Cat2Links <- Links

2) Staff -> S2Phone <- Phones

I need help querying through each tables to produce a result from links and phones in one search query.

        1st set                               2nd set
|------------------|                  |-----------------------|
| Category         |                  | Staff                 |
|------------------|                  |-----------------------|
| id int           |                  | id int                |
| name varchar(200)|                  | firstname varchar(50) |
|------------------|                  | lastname varchar(75)  |
        |                             | title varchar(100)    |
        o                             |-----------------------|
|------------------|                              |
| Cat2Links        |                              o
|------------------|                  |-----------------------|
| category int     |                  | S2Phone               |
| links int        |                  |-----------------------|
|------------------|                  | staff int             |
        o                             | phones int            |
        |                             |-----------------------|  
|-----------------------|                         o
| Links                 |                         |
|-----------------------|             |-----------------------|
| id int                |             | Phones                |
| name varchar(200)     |             |-----------------------|
| anchor varchar(200)   |             | id                    |
| keywords varchar(200) |             | desk varchar(12)      |
|-----------------------|             | wireless varchar(12)  |
                      \               | mobile varchar(12)    |
                       \              | oncall varchar(12)    |
                        \             | keywords varchar(52)  |
                         \------      |-----------------------|
                                \                       |
|-------------------------------------------------------------|
| Results would be from links (keywords) and phones (keywords)|
|-------------------------------------------------------------|

Would this be the right way to engineer this project?
