There’s another option for the table - @franklyrosalind 's Torsion LR4 table generator. But, having produced a lot of MDF scraps at this point, I’ll warn you that getting accurate cuts (especially in a newly-built, “on the floor” LR4) is maybe more of a challenge/source-of-frustration than you really want when you’re just starting out.
The “non-CNC build” LR4 table linked above is probably a good place to start - I avoided it because there’s a gap between my woodworking skills and the precision needed to make a “good” table using those plans: too many small pieces that have to to be attached to each other, too many opportunities for losing any semblance of flatness.
As for the router, I happily used a Makita for my LR3 and up until a few weeks ago in the LR4. Bought one of the Carbide 3D “clearance” routers and am really happier with it than I was with the Makita, especially for the price. (Which reminds me that I need to order a second one to have in reserve before they’re all gone…)
